As AI tools now easily solve most traditional homework problems, engineering educators face a critical inflection point in meaningful assignment design. In my discipline, electrical engineering, the traditional homework model, focused on calculating impedance, solving differential equations, or applying Kirchhoff's laws, no longer serves as an effective assessment of student understanding. Fortunately, circuit simulation technologies offer a powerful supplement that transforms how students engage with electrical engineering concepts.
Simulators like PSpice, Multisim, and MATLAB provide virtual laboratories where students can experiment without physical constraints. Rather than simply calculating a circuit's frequency response, students can manipulate component values, sweep frequencies, and observe real-time effects through virtual oscilloscopes and spectrum analyzers. This shifts homework from passive computation to active investigation. When a student asks "what happens if I replace this capacitor?" they're engaging in authentic engineering inquiry that AI (at least not yet) cannot replicate.
The educational value extends beyond mere observation. Quality circuit simulator-based assignments require students to predict behavior, troubleshoot unexpected results, and optimize designs within real-world constraints. Students might investigate why their amplifier circuit distorts at specific frequencies, determine the optimal filter topology for a given application, or debug timing issues in a digital logic system. These higher-order engineering thinking skills remain distinctly human despite AI's computational prowess.
Virtual circuit simulators democratize access to sophisticated equipment and scenarios that might otherwise be unavailable due to cost, safety concerns, or physical limitations. Consider electrical engineering students without access to $10,000 oscilloscopes, spectrum analyzers, or signal generators, through simulators they can conduct virtual experiments with professional grade virtual instrumentation. Students can work with high voltage power electronics without risk of electrocution, or experiment with expensive radio frequency components without fear of destroying them. Those with mobility limitations gain equitable access to bench electronics through virtual labs requiring no physical soldering or manipulation of components.
The boundaries of practical learning dissolve as well. Students can simulate microwave circuits operating at 77 GHz for automotive radar, design integrated circuits with nanometer-scale transistors, or test power distribution networks for satellite systems, applications that would be physically inaccessible due to fabrication requirements or specialized equipment needs. Time constraints also vanish: simulations can compress hours of thermal analysis into seconds, or slow down switching transients in power converters to observable speeds. This temporal flexibility enables understanding of electrical phenomena that operate on timescales incompatible with traditional oscilloscope measurements.
Perhaps most importantly, simulators create a psychological safety net that encourages bold experimentation. Students can intentionally exceed component ratings, create short circuits, or test failure modes without destroying expensive components or creating safety hazards. They can iterate rapidly through dozens of design variations without the time consuming process of physically rebuilding circuits. This freedom to fail productively cultivates the innovative thinking critical for solving complex electrical engineering problems that AI cannot address.
Applications will further develop collaboration features for circuit simulation platforms, creating environments that mirror real electrical engineering workplaces. Students will share designs, conduct peer reviews, and tackle complex projects like software defined radios together. This approach teaches essential professional skills including communicating design intentions, resolving different specification approaches, and building consensus, social learning experiences that AI tools cannot replicate.
For electrical engineering educators, the transition requires rethinking assessment metrics. Rather than evaluating whether a student correctly calculated a circuit's gain, we must develop rubrics that measure design robustness, component selection rationale, and troubleshooting methodology. The focus shifts from "did they get the right transfer function?" to "did they create a design that meets specifications under varied conditions?"

I agree that it makes no sense to assess students' ability to make calculations that the simulators they are familiar with already make. The problem, though, is that even the tasks you suggest (e.g., create a design that meets specifications) can be already be accomplished by a variety of generative artificial intelligence platforms. Which begs the questions: what will the electrical engineers we are training actually do when they graduate, and what will they need to know in order to do it?
Agree - I like to think (dream maybe is a better word) I'm staying one step ahead of AI and have had pretty good luck so far using a combination of PSpice and hands-on. Those days are likely numbered!
