RISC-V Pipelined Project in Chisel

This project implements a pipelined RISC-V processor in Chisel. The pipeline includes five stages: fetch, decode, execute, memory, and writeback.

The core is part of an educational project by the Chair of Electronic Design Automation at RPTU in Kaiserslautern, Germany.

Dependencies

The project requires the following dependencies to be installed:

• Scala 2.12.13
• Chisel 3.5

Usage

To run the project, simply run the following command in your terminal:

sbt run

This will generate Verilog code for the pipelined processor.

To run the testbench, simply run the following command in your terminal:

sbt test

This will simulate it using the included testbench.

Note that testHarness variables are only for testing purposes and are not necessary for the project structure.

Tools

GTKWave can be used for debugging or to verify the results.

Structure

The project is structured as follows:

• RISCV_TOP.scala: The main Chisel file containing the pipelined RISC-V processor.
• RISC_TOP_tb.scala: A ScalaTest spec that tests the pipelined processor.
