    LTSpice - what programming language does it use and how do directives hang together?

    1. So Vim has vimscript, Emacs uses Lisp - what is LTSpice doing? 2. You can use .step to update a {R} for .meas and calculate MAX/MIN etc - how is the data being passed and how do the various directives influence each other? Note in the schematic, he uses {R} and 'r' and R1 and they are all...

    Multiple-input controlled sources and Tuinenga SPICE book pg27

    https://www.pspice.com/multiple-input-controlled-sources-and-tuinenga-spice-book-pg27 (briefly how is he getting k8.v2.v3 in the images) He's trying to use POLY(dimension) to model a source using a polynomial to represent it. Form of Poly is k0 + k1x + k2x^2 and so forth so.. how the heck has...

    How do I EM-Extract a subcircuit and define a different em/drawing-layer than the original circuit in AWR?

    I have a 4-layer project in AWR/MWOffice and have built a parameterized microstrip inductor schematic (named "spiral") with a "Line Type" of layer1 that I wish to reuse on another schematic as a subcircuit (SUBCKT) on layers 1,2,4. When I place "spiral" as a subcircuit on another schematic...
