Verilator Testbench Environment (VTE)

Abstract

VTE is a library that allows fast and simple generation of C++ testers for modules written in Chisel and build an efficient interface to existing C++ based simulators. It contains Scala-based interface and C++ testbench class. Scala interface interacts with Firtl Interpreter and generates a basic set of C++ testbench files. These files contain the list of the Device Under Test (DUT) input-output ports as well as their parameters. C++ testbench provides functionalities similar to the Chisel PeekPokeTester, such PeekPokeTester as poke, expect, step functions. As a backend it uses Verilator.

Motivation

Integration with existing system simulators written in C++, e.g. SST, gem5, BookSim, etc.

Improving testing environment

VTE is a library that allows fast and simple generation of C++ testers for modules written in Chisel and builds an efficient interface to existing C++ based simulators: A. Scala-based Driver generates C++ Library (verilator APIs, DUT input/output bundles, testbench etc.) B. Test file contains similar to chisel PeekPoke Test instructions C. VTE generates the Makefile that automatically combines all generated files to create the executable
