For connectors and devices with more than 50 pins, I find a conventional schematic to be pretty useless. Often, a tabular representation makes more sense and is more readable. The following scripts manipulate a table of pins into a pseudo-schematic that can be combined with your real schematics to make a netlist, and a LaTeX table for your documentation.
When you have a component that is represented by multiple symbols, gnetlist does not handle conflicting attributes attached to the symbols very well. The following script detects conflicting attributes, generates a warning message, and replaces the conficting attribute values with "attribute_conflict".
Usage:
gnetlist -m censor-fix.scm other-gnetlist-arguments
For sorting parts lists and such, it is convenient to have the device= attribute in a consistent case. The following script uppercases it.
Usage:
gnetlist -m devupper.scm other-gnetlist-arguments
Professor Ikeda's Open-IP is a collection of subcircuits useful for mixed-signal VLSI design. See "Models" below for the associated models.
Simple, generic opamp models for circuit simulation with ngspice (and probably other SPICE dialects).
