Simulation is most valuable when it follows a clear sequence: start simple, add fidelity only where it changes decisions, and keep every model tied to a measurable goal.

Step 1 — Define the question

Before opening a schematic, write down what you need to decide:

• Can this topology meet efficiency at the target load?
• Is the control loop stable across the input range?
• Which device rating is sufficient with margin?

A vague model rarely answers a specific design question.

Step 2 — Topology and averaged behaviour

Begin with an averaged or simplified switching model to size passives and check steady-state operating points. Confirm duty cycle, inductor ripple, and capacitor voltage stress against your specs.

Step 3 — Switching and control detail

Increase fidelity where losses, EMI, or dynamics matter:

• Discrete switching events for loss and stress studies
• Controller / modulator blocks for closed-loop behaviour
• Parasitics only when they explain a measured issue

SIMBA is designed for this kind of power-electronics-centric iteration, including scripting with the Python library when you need sweeps and automation.

Step 4 — Compare, document, decide

Store scenarios (load, input voltage, temperature) and compare metrics side by side. Document assumptions so the next engineer can reproduce the study. Link results back to hardware tests as soon as a prototype exists.

Step 5 — Reuse knowledge

Successful teams turn validated models into templates: reference converters, test benches, and teaching labs. Explore Technical Resources for examples, and Academy if you are deploying SIMBA in an academic setting.

A disciplined simulation workflow does not replace the lab—it makes every lab session count.
