Spice Simulation

Use a focused testbench such as <package>/testbench/test_<scenario>.zen for one behavior: startup, enable, a protection threshold, or current limit. Reuse an existing bench when it covers the request. Run it with pcb sim <file>.zen; a separate dummy simulation is only useful when diagnosing setup problems.

Model and testbench

The leaf component needs spice_model=SpiceModel(...). Obtain a vendor model or, when appropriate, use a behavioral model with explicit limitations. Match nets to the subcircuit's declared terminal order:
