@ -65,10 +65,14 @@ This section describes the open source toolchain installation. The
current version of the toolchain has been tested on Ubuntu and Red
Hat/Rocky 8 Linux. Ubuntu works more smoothly and is recommended
unless you have a compelling need for RedHat.
Ubuntu users can install the tools by running
$ sudo $WALLY/bin/wally-tool-chain-install.sh
See wally-tool-chain-install.sh for a detailed description of each component,
or to issue the commands one at a time to install on the command line.
### Download Synthesis Libraries
For logic synthesis, we need a synthesis tool (see Section 3.XREF) and a cell library. Clone the OSU 12-track cell library for the Skywater 130 nm process:

# gcc cross-compiler (https://github.com/riscv-collab/riscv-gnu-toolchain)
# To install GCC from source can take hours to compile.
#This configuration enables multilib to target many flavors of RISC-V.
# This book is tested with GCC 12.2 (tagged 2023.01.31), but will likely work with newer versions as well.
