DRRA-based AlImp Design Tutorial (v2)

Note

This page is written for vesyla-suite version 2. It's deprecated and will be removed soon. You should only use it for old project such as DRRA characterization. For vesyla-suite version 3, please see Tutorial.

Introduction

Vesyla-suite provides two commands: vesyla and manas. Vesyla is used for compiling Matlab code to DRRA and DiMArch based SiLago fabric. Manas is used for instruction scheduling and generating RTL simulation environment.

Write the source code

Please Check the Vesyla Programming Guide v2.

Compilation

To compile a program that is purely matlab script by using Vesyla and Manas, use the following command:

vesyla -o $PathToOutputDirectory $PathToMatlabFile
manas -o $PathToOutputDirectory -t json $PathToOutputDirectory/filegen

RTL simulation

Vesyla also generates environment for RTL simulation. It's in $OUTPUT/filegen/sim_vsim. However, you can't directly simulate it under QuestaSim because you need to specify the path to the DRRA+DiMArch fabric.

To specify the path to the fabric, use the command:

export FABRIC_PATH=$PathToFabric

Then, you can use Questasim to run the simulation script genereated by Vesyla:

cd $OUTPUT/filegen/
vsim -c -do run_gui.do
