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
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)
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.
mill raytracer.test
or
sbt test
