Want to simulate your Wishbone peripherals without the overhead of synthesizing or simulating the full ZPUino Soft Processor?
We’ve been working on porting a stepper control core to work as a wishbone peripheral on the ZPUino. To help us out with this process Alvie put together a really cool wishbone testbench that lets us simulate the core by manually writing to the wishbone registers. This is a very lightweight solution that lets you verify your wishbone peripherals without the overhead of simulating or synthesizing the full ZPUino Soft Processor!
Feel free to get the code for this on github.
Many thanks to Jack and Alvie for all their work on this! If you’ve got anything to add to the discussion, please do so in the comments section.
