What happened and what to do
Published on December 11, 2025, the article describes testing the custom Mrav CPU core using cocotb and Python scripts to control RTL simulation. The approach also uses a Python class to model RAM, allowing the CPU to be exercised without writing Verilog testbenches or a RAM controller.
A company developing hardware could apply this approach to structure automated RTL tests, simulate memory components, and track results in continuous integration. Implementation could include reproducible test cases, failure logging, and execution monitoring, without requiring an AI use case.
