ZPUino Wishbone Simulator

[Jack Gassett]

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!

 

The code is located on github.

Hi,

this simulation project is very usefull as the ZPUino is quite long to synthesize.

 

Juste a remarque,

I used this simulation project to simulate a custom periferal of my own based on the exemples of this topic:

The exemple 1 is not working with the simulator because of "Asynchronous acknowledge" i guess.

I had to move my periferal on the exemple 2, and it works perfectly.

Let me see if I can modify the WB injector to support asynchronous acknowledges.
