00:04.867 -->
00:09.091Hello
00:09.318 -->
00:12.813there, everyone. Welcome to episode
00:13.313 -->
00:17.715number 693 of this here electronic
00:17.796 -->
00:21.977engineering podcast called Amelia's Weekly
00:22.090 -->
00:26.811Fish Fry, brought to you by eejournal.com
00:26.924 -->
00:29.866and written, produced, and hosted by yours truly, Amelia Dalton.
00:32.813 -->
00:37.203A lot of folks are talking about agentic AI like it's some kind
00:37.703 -->
00:39.815of magic shortcut for engineering,
00:40.423 -->
00:43.868promising lightning-fast automation and effortless
00:44.368 -->
00:48.162results. But in the world of high-stakes systems,
00:48.691 -->
00:52.008speed doesn't mean much if you can't trust the output.
00:52.825 -->
00:56.446If your AI is doing its own thing, disconnected from
00:56.946 -->
01:00.019the simulation and verification we all rely on,
01:00.998 -->
01:04.227How can you really ever trust it? My guest
01:04.727 -->
01:08.790today is Jason Guidella, Senior Principal Technologist
01:08.951 -->
01:13.272at MathWorks. And we're moving past this going
01:13.385 -->
01:17.048faster hype to look at the actual challenges
01:17.305 -->
01:21.064of deployment. Jason and I discuss what
01:21.177 -->
01:25.691breaks when you try to use agentic AI in complex
01:25.755 -->
01:29.846engineering systems. Where today's agentic AI
01:30.346 -->
01:33.100tools tend to fall short for engineering teams,
01:33.774 -->
01:37.461and why grounded AI, the kind that actually works
01:37.961 -->
01:41.692within your existing engineering workflows, is the
01:41.773 -->
01:45.027only way to go. So without further ado,
01:45.395 -->
01:48.762please welcome Jason to Fish Fry. Hi,
01:48.842 -->
01:52.048Jason. Thank you so much for joining me. Thanks,
01:52.064 -->
01:55.337Amelia. Great to be here with you. Excellent. Okay,
01:55.433 -->
01:59.450so Jason, everyone talks about how much faster agentic
01:59.579 -->
02:03.499AI can make engineers, but is speed
02:03.596 -->
02:07.597actually the hard part? Speed is what gets the attention,
02:07.950 -->
02:10.328and it's an important part of the overall story.
02:11.308 -->
02:14.618However, agentic AI can create code,
02:14.683 -->
02:17.880it can modify models, it can set up simulations,
02:17.977 -->
02:21.463tune parameters, it can do so much. But that's not what
02:21.963 -->
02:25.173engineers need only. Engineering is much more
02:25.237 -->
02:28.433than just that. And that's not the hard part. The harder question
02:28.933 -->
02:32.689is whether that work that is being done can be evaluated with inside
02:33.189 -->
02:36.623an engineering workflow. So this is where I think we need
02:37.123 -->
02:40.317to be clear on what the role of the agent is. The agent can help
02:40.817 -->
02:44.734create a model. It can, it can propose a change, create an app, maybe create
02:45.234 -->
02:48.762test cases and orchestrate a workflow. But it shouldn't be replacing
02:48.906 -->
02:52.290deterministic engineering tools. It should not make
02:52.790 -->
02:56.283up a simulation result. It should not replace static code analysis.
02:57.004 -->
03:00.693It should call the right deterministic tools with inside
03:01.193 -->
03:05.071our engineering workflow to do those things. So I think the real reason
03:05.087 -->
03:08.246here is simple. Engineering evidence has to be repeatable.
03:08.406 -->
03:11.982If I give the same model, the same code, the same requirements,
03:11.998 -->
03:15.092and the same test inputs, to an analysis workload, it needs
03:15.124 -->
03:18.698to give me the same result back. And that determinism is
03:18.810 -->
03:22.560what allows engineers to use the evidence in
03:23.060 -->
03:26.374a decision process. So a concrete example that I
03:26.823 -->
03:30.412like to use, it's a search and rescue system that's called
03:30.912 -->
03:34.611LifeSeeker, and it's made by Sentum. And it's at one level, you can
03:34.739 -->
03:37.607really think of this system, it's a very easy system to understand.
03:37.736 -->
03:41.022Someone is lost maybe in the Alps. A search team is trying
03:41.522 -->
03:45.222to locate them, and the system helps find them really a lot,
03:45.270 -->
03:49.069much faster. Now, from an engineering perspective,
03:49.502 -->
03:53.157that's a highly interconnected system. It's involving RF signals,
03:53.269 -->
03:55.561signal processing, communications,
03:55.754 -->
03:59.168aircraft motion, geolocation algorithms,
03:59.281 -->
04:02.567embedded software, and operator workflows. And so this
04:03.067 -->
04:06.655is a really complex system. And you want an
04:07.155 -->
04:10.710agentic workflow here to help you develop it, but you only
04:10.822 -->
04:15.038want it to do that work if it's within the way engineers
04:15.391 -->
04:18.757are building and evaluating that full system. So the way I like to
04:19.257 -->
04:22.893frame it is that the bottleneck is shifting. Before,
04:22.909 -->
04:26.099the first question was that the— can the AI create the engineering
04:26.195 -->
04:29.449work? And I think that's increasingly becoming, yes, it can.
04:30.235 -->
04:33.906So the next question is, can that work be evaluated in the
04:34.406 -->
04:37.401same workflow that engineers already use to make design decisions.
04:38.572 -->
04:42.807So, so like, if I take that LifeCycle Seeker example
04:43.307 -->
04:47.187a little further, so let's suppose the agent has proposed a new improvement
04:47.685 -->
04:51.872to the signal processing algorithm that's being used to locate a lost
04:52.372 -->
04:55.915signal, cellular signal. Now, that sounds valuable, and it
04:55.947 -->
04:59.621should be evaluated. However, the engineering team has
04:59.653 -->
05:02.685to do that evaluation across the whole system.
05:03.086 -->
05:06.595Does it work under a weak signal condition? Does it change system latency?
05:07.108 -->
05:10.586What about the computational effects? These are all things that need
05:11.355 -->
05:14.848to be resolved. It can't be just simply, does it work better?
05:15.361 -->
05:18.293What I needed to do is I wanted to run the simulation,
05:18.486 -->
05:22.460execute the relevant tests, check the analysis, and preserve
05:22.492 -->
05:26.081that traceability needed to understand if this change is happening.
05:26.434 -->
05:30.234So for me, the hard part here is It's not simply creating
05:30.347 -->
05:33.991engineering output faster, it's creating output that fits into
05:34.023 -->
05:36.848the workflow engineers use to generate deterministic,
05:37.313 -->
05:39.866repeatable evidence here. So, Jason,
05:40.219 -->
05:43.718what's different about using agentic AI in engineering
05:44.216 -->
05:47.378versus using it to write code or documents?
05:47.924 -->
05:51.664So I think with the difference here is with engineering work, it's tied
05:51.777 -->
05:55.341to system behavior, and engineering evidence has to be
05:55.373 -->
05:58.820repeatable here. So when I look at AI to help me write a
05:59.320 -->
06:02.956document, a person can quickly review whether the language communicates
06:03.004 -->
06:06.643what you intended it to say. With AI,
06:07.172 -->
06:10.587if it can help you create code, that code
06:10.683 -->
06:13.905has to still be tested. And in an embedded system
06:14.370 -->
06:17.111like a signal processing communication control system,
06:17.897 -->
06:22.097that chain really happens and stays local to that particular component.
06:22.803 -->
06:26.354And so that software change can affect timing. It can
06:26.854 -->
06:30.772affect the detection performance. It could change the actual way the physical system
06:30.836 -->
06:34.210reacts, right? So all of these things need to be
06:34.710 -->
06:38.870taken into consideration. And so the engineering question is not simply, did the AI
06:39.370 -->
06:43.384create something that looks right? It's really that, how does that change behave
06:43.448 -->
06:46.822in the system? And what evidence do we have to prove that? So I
06:47.322 -->
06:50.419think this is where the agent role matters. I want the agent to help me
06:50.919 -->
06:54.572create a model, create the supporting code, maybe suggest test cases
06:54.941 -->
06:58.085and orchestrate, say, an analysis sequence here.
06:58.838 -->
07:03.152But when it comes to evidence, the agent should be calling established engineering
07:03.184 -->
07:07.434tools, simulation, verification, code generation, static code analysis,
07:07.771 -->
07:11.251test frameworks, and such. You know, we've talked about
07:11.508 -->
07:15.164this, I think, and you too, Amelia, have talked about that with my colleagues over
07:15.212 -->
07:18.789the past few months, digital twins, model-based system engineering,
07:19.366 -->
07:22.803RF and software-defined systems. And those conversations really
07:22.915 -->
07:26.497were all about a similar flow, system-level visibility,
07:26.673 -->
07:29.789virtual validation, simulation before moving
07:29.821 -->
07:32.952to hardware, and then reducing that integration risk.
07:33.755 -->
07:37.818And so that's, that's the important piece here, I think, is that the agent can
07:37.834 -->
07:41.560help only when it's inside and participates
07:41.608 -->
07:44.997within the engineering workflow rather than operating as a separate
07:45.497 -->
07:48.880source of truth. All right. So Jason, why are
07:48.928 -->
07:52.345engineering workflows built around simulation,
07:52.521 -->
07:55.794verification, and traceability in the first place?
07:56.468 -->
08:00.205I think it really comes down to engineers need objective evidence.
08:00.333 -->
08:03.221So simulation gives evidence about the behavior.
08:03.606 -->
08:07.696Verification gives evidence that requirements or design expectations
08:08.196 -->
08:11.851are being met. Testing gives evidence that the change
08:11.867 -->
08:15.843works under defined conditions. And you need traceability to
08:15.859 -->
08:20.010connect that original intent from the design to the implementation
08:20.202 -->
08:24.017and to the results that were used to evaluate it. But there's also another important
08:24.209 -->
08:27.270point here. This evidence has to be deterministic
08:27.559 -->
08:31.341and reproducible. If the same model and same test conditions produce
08:31.841 -->
08:35.476different conclusions every time, that's not a basis for any engineering
08:35.492 -->
08:39.259decision-making, right? And this is why existing engineering tools do
08:39.275 -->
08:42.576matter. I need a simulation engine. I need a code generator
08:42.624 -->
08:46.891or a study. Analysis tool or a test framework here because they
08:46.955 -->
08:50.549operate within defined inputs, defined configurations,
08:50.565 -->
08:53.966and produce repeatable outputs. And those tools make
08:54.030 -->
08:56.404that needed evidence that engineers have.
08:57.302 -->
09:00.703When you look at it like an agentic AI can help
09:01.203 -->
09:04.537set up the workflow, it can help identify what needs to be checked,
09:04.778 -->
09:07.922it can help create the artifacts or call the next step.
09:08.628 -->
09:11.885But it should be calling the deterministic tools to produce the evidence
09:12.077 -->
09:15.849and it shouldn't be making that up. And why workflows need to exist
09:16.349 -->
09:20.216in the first place is that the team needs this repeatable evidence
09:20.650 -->
09:24.295that the system behaves as expected, not just as an AI
09:24.359 -->
09:27.377explanation that sounds plausible in the first place.
09:28.373 -->
09:31.664And, and I think when you look at it, this connects
09:32.164 -->
09:35.951back to our core ideas with model-based design and even model-based system
09:36.000 -->
09:40.255engineering, that models are not just documentation. They are executable
09:40.755 -->
09:44.731representations that help team evaluate behavior earlier,
09:44.827 -->
09:48.885it helps you explore alternatives and understand the effects of changes
09:48.917 -->
09:52.236before deployment. Absolutely. So Jason,
09:52.445 -->
09:55.524what breaks when you try to use agentic AI in
09:55.636 -->
09:59.068a complex engineering system? So I think what
09:59.084 -->
10:03.558breaks is often the connection between what the AI-generated
10:03.734 -->
10:07.439output was made and the engineering evidence needed to
10:07.939 -->
10:11.798evaluate that output. So let's stay with the LifeSeker
10:11.991 -->
10:16.061customer example. So suppose an agent proposes
10:16.173 -->
10:20.067a change to improve that signal detection or location accuracy.
10:20.660 -->
10:23.881This is going to be a very useful change to have. But now the engineer
10:24.381 -->
10:28.015needs traceability and impact analysis to understand what
10:28.515 -->
10:31.557requirement does this change relate to? What part of the model
10:32.057 -->
10:36.348changed? What tests should be rerun? You know, what downstream
10:36.364 -->
10:39.456behavior might be affected and so on.
10:40.129 -->
10:43.686This is also where determinism matters. The agent
10:44.215 -->
10:47.547should not answer those questions by inventing its own analysis.
10:48.140 -->
10:51.393It should call the tools the engineers use for those tasks.
10:51.601 -->
10:54.341It should run the simulation. It should invoke the tests.
10:55.030 -->
10:58.282It should use the static analysis tools. It should preserve
10:58.314 -->
11:01.727the links to requirements and results so engineers can inspect
11:01.839 -->
11:05.370the impact of what might happen. And if the agent makes
11:05.434 -->
11:09.209the change outside of that workflow, engineer has to reconstruct
11:09.290 -->
11:12.728all of this manually. They need to inspect the change,
11:12.824 -->
11:16.536map it back to the requirements, determine what simulation and tests are
11:17.036 -->
11:20.231relevant, run the analysis and compare results. And so all that
11:20.731 -->
11:24.537productivity that you've, you've gained, you've just now lost it on the verification
11:24.649 -->
11:29.244side. And this issue is not just whether AI produced
11:29.744 -->
11:33.900a good answer. The issue is whether the workflow is preserved, traceability, the impact
11:34.400 -->
11:38.138analysis, and the repeatable evidence needed to really evaluate that answer.
11:38.764 -->
11:42.906So kind of following up on that, Jason, why isn't it enough
11:43.098 -->
11:46.790for agentic AI to just give engineers the right
11:47.290 -->
11:50.755answer? Because in engineering, the right answer without supporting evidence
11:51.255 -->
11:54.720is still incomplete, right? It's not an answer. I like to say sometimes,
11:54.977 -->
11:58.525show me the money. Don't just talk about it. I'll eat everything.
11:58.669 -->
12:01.865Show me the money. Show me the evidence. But really, more seriously,
12:02.057 -->
12:05.846engineers need to understand what changed, what assumptions were made,
12:05.911 -->
12:08.929what simulations were run, what tests passed or failed,
12:09.363 -->
12:12.413and whether the result is traceable back to that design intent.
12:13.280 -->
12:16.235That's especially important in embedded signal processing,
12:16.331 -->
12:18.884communication, and control systems. In these systems,
12:19.703 -->
12:22.914the behavior comes from the interactions between the algorithm, the software,
12:22.994 -->
12:26.029the hardware, the physical dynamics, sensors, actuators,
12:26.542 -->
12:30.089communication links, the real-world operating conditions. So if an
12:30.137 -->
12:32.770agent proposes a new signal processing method,
12:33.604 -->
12:37.215I do not only want that method, I want to know how it
12:37.715 -->
12:41.533performs across representative signal conditions. So I want to know whether it affects
12:42.033 -->
12:45.641latency or resource usage, right? I want to know which test cases were
12:46.141 -->
12:48.803run. And I want to know whether it still satisfies my requirements.
12:49.413 -->
12:52.494And I want those results to come from
12:52.527 -->
12:56.411the tools engineers already depend on. If the question is whether generated
12:56.796 -->
13:00.536code matches the model, use the code generation and verification
13:00.648 -->
13:04.500workflow. If the question is whether code has defects,
13:04.741 -->
13:08.721run the static code analysis. If the question is how does the system
13:08.753 -->
13:12.188behave, run the simulation. And the question is whether
13:12.688 -->
13:16.521the requirements are still being met, check the traceability and test results, right? And this
13:17.021 -->
13:21.401is where really MATLAB and Simulink are directly relevant. Engineers have used MATLAB
13:21.901 -->
13:25.305and Simulink to model systems, simulate behavior, analyze results,
13:25.434 -->
13:28.406create tests, and connect requirements,
13:28.422 -->
13:31.780generate code, all these things, right, to support that overall
13:32.117 -->
13:35.652verification workflow. And for agentic tools to
13:36.152 -->
13:39.878be useful in that environment, those tools need access to that same engineering
13:39.910 -->
13:43.188context. It needs to work with the
13:43.688 -->
13:47.349models, the simulations, the code, the tests, and workflows engineers already use.
13:48.103 -->
13:51.774And so that's why we made— released the MATLAB MCP
13:52.274 -->
13:55.813Core Server and the MATLAB Agentic Toolkit and Simulink Agentic Toolkits.
13:56.518 -->
14:00.366They're not replacing MATLAB and Simulink with an AI agent, but they're
14:00.866 -->
14:04.021giving the agent a structured way to use MATLAB and Simulink effectively,
14:04.453 -->
14:07.387to call the right tools, inspect artifacts, run analyses,
14:07.740 -->
14:11.747and move work through the workflow. So the goal is not for AI that
14:12.247 -->
14:16.139simply gives an engineer an answer. The goal is that the AI is helping create
14:16.639 -->
14:20.694the answer and use the right deterministic engineering tools to produce the evidence needed
14:21.047 -->
14:24.241to evaluate it. So Jason, where do
14:24.741 -->
14:28.383you think today's agentic AI tools tend to fall short
14:28.495 -->
14:31.898for engineering teams? Many agentic AI
14:32.043 -->
14:35.654tools can create content or automate tasks,
14:35.815 -->
14:39.362but engineering tools need more than task automation.
14:40.053 -->
14:43.359An agent has to do more than create the code or suggest a model change.
14:43.761 -->
14:47.661They are very useful activities and capabilities that will help speed,
14:48.015 -->
14:51.788right, as we mentioned. However, if the agent is disconnected from
14:51.852 -->
14:55.449the engineering environment, it may not have the right context
14:55.561 -->
14:58.773or skills needed to work in a way that engineers can use it.
14:59.575 -->
15:03.188It may not understand the system model. It may not know what the requirements
15:03.688 -->
15:07.026are. It may not know which simulations matter. It may not know
15:07.106 -->
15:10.638which tests are relevant, or it may not even know how a
15:11.138 -->
15:13.946change affects other parts of the system. And these are, you know,
15:14.122 -->
15:17.541so important. And I think on top of that, if it doesn't know
15:17.621 -->
15:21.297which deterministic tool to use to produce the evidence needed,
15:21.473 -->
15:25.197then again, you're, you're broken from this overall workflow. If we go
15:25.261 -->
15:28.696back to our Life Seeker example, if the agent is used
15:29.196 -->
15:31.167to create that signal processing algorithm,
15:32.483 -->
15:36.416that's useful, but its usefulness only depends on much more
15:36.916 -->
15:40.621than just how it creates that code. The team needs to know if that
15:40.669 -->
15:44.361code behaves in the system. They need to test it against
15:44.861 -->
15:48.438the signal conditions and geolocation performance and embedded
15:48.938 -->
15:51.985constraints and timing constraints and system-level requirements.
15:52.547 -->
15:56.576This is where I would distinguish between generic automation
15:57.076 -->
16:00.476and engineering automation. I would say a generic automation is that the
16:00.492 -->
16:04.264agent completed a task, and the engineering automation is that
16:04.764 -->
16:08.198the agent completed that task in a way that it is connected to the
16:08.698 -->
16:12.744workflow used to evaluate that task. That is why that context and skills
16:13.178 -->
16:16.631matter, and that's why agents need the right context
16:17.131 -->
16:21.016from the engineering environment that they're working within. And that's the way they can
16:21.113 -->
16:24.405work most efficiently and correctly and have access to the
16:24.905 -->
16:28.742right tools. So for MATLAB and Simulink, that means structured
16:29.242 -->
16:33.141access to the models, the simulations, the tests, and so on. And that's where the
16:33.641 -->
16:37.900MATLAB MCP Core Server and the Agentic Toolkits help. They help agents
16:38.044 -->
16:41.345operate through engineering tools and workflows rather than around them.
16:41.761 -->
16:44.582So Jason, I've heard the term grounded AI.
16:44.806 -->
16:48.427So talk to me about this. When I
16:48.619 -->
16:52.625hear that term, when I use that term, I mean AI that
16:52.705 -->
16:56.807is operating within that engineering context that engineers already use
16:57.307 -->
17:01.134to design, simulate, test, verify, and deploy systems. It is grounded
17:01.294 -->
17:04.677in the models. It is grounded in the requirements. It is grounded in
17:05.177 -->
17:09.229simulation results, test cases, verification workflows, engineering constraints,
17:09.309 -->
17:12.692and so on. I think also grounded AI for me also
17:12.756 -->
17:16.491means respecting the boundary between what an AI should
17:16.619 -->
17:19.825do and what deterministic engineering tools should do.
17:20.595 -->
17:24.314The agent can help again, create a model. It can propose a
17:24.362 -->
17:28.083design change. It can create an app. Suggest the right test cases
17:28.131 -->
17:31.439to make, and it can orchestrate workflow steps for me.
17:32.097 -->
17:35.533It could also help explain the results and, and help engineers navigate the
17:36.033 -->
17:39.675complexity of an overall design. But when the workflow requires
17:39.787 -->
17:43.159engineering evidence, the agent should call the appropriate tool.
17:43.560 -->
17:47.638It should run the simulation, it should invoke that test, it should use
17:48.138 -->
17:50.994the right code generator, run the static analysis, and so on.
17:51.588 -->
17:54.956The agent should not become a probabilistic replacement
17:55.456 -->
17:59.300for their steps, right? And I think this is a really important distinction because engineering
17:59.364 -->
18:02.763evidence has to be repeatable. Same input, same configuration,
18:02.811 -->
18:06.306same tool, same result. That determinism is
18:06.402 -->
18:09.464what makes engineers make decisions from that evidence.
18:10.105 -->
18:13.888I think this is where MATLAB and Simulink and the MATLAB MPC Core Server,
18:13.937 -->
18:17.672the MATLAB Agentic Toolkit, the MATLAB and the Simulink Agentic Toolkit
18:17.784 -->
18:21.587come together. MATLAB and Simulink provide that engineering environment.
18:21.876 -->
18:25.600The core server and agentic toolkits give the agents that
18:26.100 -->
18:30.063structured way to access those capabilities and use them as part
18:30.143 -->
18:33.369of an overall engineering workflow. I'll come back to my Life
18:33.869 -->
18:37.575Seeker example. The grounded AI would not just propose a
18:37.623 -->
18:41.588better algorithm, it would help make the proposal in the
18:41.700 -->
18:45.247engineering environment where the team can evaluate its effect on
18:45.747 -->
18:49.422the RF behavior, the signal processing, the embedded constraints,
18:49.503 -->
18:53.036the timing, and system-level requirements. And that is the shift
18:53.536 -->
18:56.955I think matters. Agentic AI becomes more useful when
18:57.455 -->
19:00.986it does not bypass the engineering workflow, but participates in it.
19:02.255 -->
19:06.398All right, Jason, before I let you go, it's time for your off-the-cuff question.
19:06.944 -->
19:10.221So if you could have one meal right now, it doesn't
19:10.721 -->
19:13.673matter if it's on the other side of the world, you need a passport to
19:14.173 -->
19:18.327get there, what would you have? I would have Moreton Bay bugs on
19:18.360 -->
19:21.641the Esplanade in Cairns in Far North Queensland where
19:21.674 -->
19:24.970I grew up. Now, I realize this name sounds a
19:25.470 -->
19:28.955little disgusting if you've never heard of it before, but they are not really bugs
19:29.084 -->
19:32.988in that sense. They're a type of slipper lobster from Australia
19:33.567 -->
19:36.860and they are absolutely delicious. They're sweet, they're delicate,
19:36.924 -->
19:40.153and honestly about as good as seafood gets really.
19:40.700 -->
19:44.350And when they're grilled, with garlic and butter. Yeah,
19:44.494 -->
19:48.188having that sitting outside by the water in cans, that's pretty hard
19:48.688 -->
19:52.557to beat. And yes, I do promise they taste much better than they sound.
19:52.926 -->
19:56.540You had me a little scared there for a minute, Jason, but that sounds absolutely
19:57.040 -->
20:00.908delicious. Well, this was super cool. Thank you so
20:01.408 -->
