Spice Simulation Use a focused testbench such as for one behavior: startup, enable, a protection threshold, or current limit. Reuse an existing bench when it covers the request. Run it with ; a separate dummy simulation is only useful when diagnosing setup problems. runs the executable in batch mode in the testbench's directory and stops it after 5 seconds. Without , a successful run prints only that it passed. Model and testbench Every component that is not DNP needs a SPICE model. The stdlib generics, such as resistors, capacitors, inductors, ferrite beads, crystals, diodes, LEDs, and TVS d…
