Spack Package for VTR

Verilog to Routing (VTR) is a widely-used open-source CAD flow for exploring and targeting diverse FPGA architectures.

This repo demonstrates the proof-of-concept of building VTR using Spack on some outdated platforms (which are too old to get dependencies right with legacy methods):

cd /path/to/vtr-spack-package/
docker build -t vtr-poc-centos --build-arg OS_BASE=centos --build-arg OS_VERSION=centos7 .
docker build -t vtr-poc-ubuntu --build-arg OS_BASE=ubuntu --build-arg OS_VERSION=18.04 .

Usage

To build VTR (in CentOS 7 for example):

# 1) Install essential requirements for Spack
yum install -y git python3 gcc gcc-c++ make patch bzip2 unzip time

# 2) Get Spack from GitHub
git clone https://github.com/spack/spack.git

# 3) Activate Spack
. /path/to/spack/share/spack/setup-env.sh

# 4) Config compilers
spack compiler find

# 5) (optional) Add C++14 compiler (e.g., GCC7)
spack install -j$(nproc) gcc@7
spack compiler add $(spack location -i gcc@7)

# 6) Install VTR
spack install -j$(nproc) vtr

# 7) Load VTR before using it
spack load vtr

# 8) Test VTR
cd $VTR_ROOT
./run_reg_test.py parmys_reg_basic
./vtr_flow/scripts/run_vtr_task.py regression_tests/vtr_reg_basic/basic_timing

Note: For Step 6, only after spack/spack#39298 is merged into the Spack mainstream, can users install VTR directly through spack install vtr. Otherwise, please manually copy the /path/to/vtr-spack-package/package.py file to the Spack local codebase at /path/to/spack/var/spack/repos/builtin/packages/vtr/ first, and install VTR via spack install vtr then.

In theory, this method of building VTR can be applied to any platform that supports Python 3 and Spack.
