Help Creating a Subcircuit Model with Probing and External Parameters

[Mike2]

Hi everyone,

I already have a complete schematic that I’d like to turn into a subcircuit so I can use it inside a larger circuit. In addition to that, I need to:

1. Probe internal signals within the subcircuit when it’s used in the top-level design.
2. Make component values like resistors (R), inductors (L), and capacitors (C) adjustable from outside the subcircuit, so I don’t have to edit the internal schematic every time I want to change them.

If anyone has a guide or tutorial that explains how to do this in Qspice . I’d really appreciate it!

Thanks a lot!

#1. Probe internal signals for .subckt (hierarchical block or sub-circuit)

#2. Passing parameters into .subckt (hierarchical block or sub-circuit)
