YONGA-LZ4 Decoder
Table of contents
Overview
YONGA-LZ4 Decoder is an implementation of the decoder of the popular LZ4 compression algorithm.
Setup
export PDK_ROOT=<pdk-installation-path>
export OPENLANE_ROOT=<openlane-installation-path>
cd $UPRJ_ROOT
export CARAVEL_ROOT=$(pwd)/caravel
make install
Running Simulation
WISHBONE Test
- This test is meant to verify that we can read and write to the YONGA-LZ4 Decoder through the WISHBONE port. The firmware first writes a compressed data stream to input FIFO of the YONGA-LZ4 Decoder, then reads decoded data stream from output FIFO of the YONGA-LZ4 Decoder.
To run RTL simulation,
cd $UPRJ_ROOT
make verify-wb_test
Hardening the User Project Macro using OpenLANE
# Run openlane to harden user_proj_example
make user_proj_example
# Run openlane to harden user_project_wrapper
make user_project_wrapper
Checklist for Open-MPW Two Submission
- [x] The project repo adheres to the same directory structure in this repo
- [x] The project repo contain info.yaml at the project root
- [x] Top level macro is named
user_project_wrapper
- [x] Full Chip Simulation passes for RTL and GL (gate-level)
- [x] The hardened Macros are LVS and DRC clean
- [x] The hardened
user_project_wrapper
adheres to the same pin order specified at pin_order - [x] XOR check passes with zero total difference.
- [x] Openlane summary reports are retained under ./signoff/
