Demo project + video: Surfer waveform viewer with Questa and VUnit
Surfer is a fast, modern open-source waveform viewer, written in Rust and GPU-rendered, with mappings and decoders that turn raw signal values into readable labels. This demo project shows how to use it alongside Questa or ModelSim.
In the video, I walk you through the example in Windows and Linux and show how to use Surfer’s mappings and decoders on VHDLwhiz’s existing RISC-V project, all while simulating in Questa.
