Overview

This repository runs the following pipecleaner designs through a digital physical design flow using Design Compiler and Innovus with the SkyWater open source 130nm PDK.

  • GcdUnit - computes the greatest common divisor function, consists of 100-200 gates
  • SramUnit - uses an OpenRAM generated SRAM, plus a simple counter that supplies addresses to it

Setup

To run this flow, please install the following dependencies first in this order:

  1. skywater-pdk

Get SkyWater PDK:

git clone https://github.com/google/skywater-pdk.git
cd skywater-pdk

The cell libraries are in submodules that need to be checked out independently:

git submodule update --init libraries/sky130_fd_sc_hd/latest
git submodule update --init libraries/sky130_fd_pr/latest
git submodule update --init libraries/sky130_fd_io/latest
