Gal Simulator

v1.0 tool

A browser based PAL/GAL simulator.

Overview

A single-file, browser-based simulator for GAL16V8, GAL20V8, and GAL22V10 PLD fuse maps (JED files). Load a real JED, watch it decode into per-pin logic equations, then flip switches and pulse the clock on a virtual breadboard to see exactly how your design behaves before you burn it into a chip.

Also works with the Microchip/Atmel ATF16V8C / ATF20V8 / ATF22V10C parts, since they’re JEDEC-fuse-map-identical to the Lattice originals.

  • GAL or ATF support — Works with the Microchip/Atmel chips or the orignal Lattice GAL chips.
  • Auto-detect — Auto-detects GAL16V8 / GAL20V8 / GAL22V10 from the JED file.
  • Examples built in — Comes with built in exampels for GAL16V8, GAL20V8, GAL22V10
  • 100% local — One HTML file, open it in a browser and it works.

Why

I wanted to simulate GAL logic for a computer project, I am not aware of anything that does this in a browser.
