galpal - Verilog GAL and PAL models
-----------------------------------

These models are designed to assist in simulating obsolete 5v GAL and
PAL series parts.

To build a model from a JEDEC fusemap, simply copy your fusemap to
this directory as 'Model_Name.jed', and run:

$ make Model_Name.v

The Makefile will generate a Verilog model from your fusemap, where the
fusemap is encoded as a constant integer string in the model.

Generated models only require the 'galpal_22V10.v' or 'galpal_16R8.v'
helper models for instantiation (in the 'rtl' subdirecory).

Example 22V10 and 16R8 JEDEC fusemaps are in the 'test' directory.

DIP pin ordering for known JEDEC fusemap types below:
