Documentation

A documentation for the Ray Tracer Datapath can be found in a PDF file in the release where the following are discussed:

• Supported operations
• IO specification
• Configurable parameters
• Dataflow of pipeline stages
• Hardware assets
• Design choices
• Description of source files

Prerequisites

The code in this project was tested with verilator version 4.038 and sbt version 1.8 or mill version 0.10.12.

• verilator (for running the testbenches)
• sbt (optional) (for building the project with SBT)

How to run the test bench

Test top module only.

mill raytracer.test.testOnly raytracer_datapath.Datapath_test

or

sbt test:testOnly raytracer_datapath.Datapath_test

Mill should be ready to use because a wrapper file for mill 0.10.12 is included with this project.

Test top module as well as individual components.

mill raytracer.test

or

sbt test
