Release Notes

A simulator that enables more powerful simulation in ChiselSim. A simulation can be customised by choosing a sequence of settings. For instance, it enables the generation vcd traces, saving the working directory of svsim, and passing options to firtool from ChiselSim.

Hello, I realized that the ParametricSimulator I made for my project (Tywaves) may boost the features of ChiselSim.

I created it since I needed to do the following things from ChiselSim:

• Get a Vcd file
• Save the working directory of svsim
• Customize the firtool compilation for the circuit simulated

Apart from these 3 basic options, the simulator offers more settings with support for extension. A full list of the current settings is available here.
