Custom IC Creator

cIcCreator is a compiler for integrated circuits.

cIcCreator reads a JSON object definition file, technology rule file and a SPICE netlist (assumes same name as object definition file) and outputs a cic description file (.cic).

Use cicpy (https://github.com/wulffern/cicpy) to transpile the .cic file to other formats.

Getting started

First clone the repo

git clone https://github.com/wulffern/ciccreator
cd ciccreator
git clone https://github.com/wulffern/ciccreator-bin release

In the release folder, you hopefully find the binary for your platform.

There are three input files needed to run the compiler

• Technology file

• Object definition file

• Netlist

The description below is for MacOS. For other OS replace the .darwin with the binary that applies to your platform.

release/cic.darwin-latest examples/SAR_ESSCIRC16_28N.json examples/tech.json SAR_TEST

The output of the compiler will be SAR_TEST.cic

To view the output, do

release/cic-gui.darwin-latest SAR_TEST.cic examples/tech.json

The examples/routes.json show some examples of the routings, and other options

release/cic.darwin-latest examples/routes.json examples/tech.json routes
release/cic-gui.darwin-latest routes.cic examples/tech.json
