Ubuntu compilation

This tutorial has been tested under Ubuntu 18.04

Clone the OpenFPGA git repository:

git clone --recurse-submodules https://github.com/LNIS-Projects/OpenFPGA.git

Go to the VPR directory and build the tool:

cd ./OpenFPGA/vpr7_x2p/vpr/ make

This will generate vpr and a libvpr.a file.

Enhancements of VPR were made. In order to see them just type:

./vpr

This will show the different options that can be used. Our modifications concern the options starting with fpga_spice and fpga_verilog.

A script is already prepared in the folder to test FPGA-SPICE:

./go.sh

This script uses the enhanced version of vpr with some new options such as --fpga_spice_print_top_testbench which automatically generates a testbench for the full FPGA and --fpga_verilog_dir which allows us to choose the destination directory for the verilog output we generate. For more informations on how the new commands work, please visit OpenFPGA Options FPGA-SPICE.

As a result, we get a new folder, /verilog_test, which contains the verilog code. The name_top.v contains the full FPGA we just created. Three other folders are created, lb, routing and sub_modules. lb contains the different CLBs used in the architecture. routing contains the different connection blocks, the switch boxes and the wires. sub_modules contains the different modules needed in the architecture.
