21:19 <Guest41> Hi folks, a beginner question: what's the recommended way to simulate modules that rely on the platform? Should I pass the real platform to amaranth.cli.main(), or is there a "test" platform defined somewhere? If I pass the real platform, modules that determine the clock frequency using platform.default_clk_frequency end up inconsistent with the

21:19 <Guest41> simulation clock frequency configured by the command line args.

21:32 <d1b2> <dragonmux> don't know if this is per-se the 'recommended' way, but it works - and that is, construct a fake platform that provides sim versions of the things you need, use Fragment to take the sim top-level and pass it the platform, and pass the results to the simulator

21:33 <d1b2> <dragonmux> 'sec and we'll get you a couple of links showing how we do this

21:33 <d1b2> <dragonmux> https://github.com/bad-alloc-heavy-industries/dragonBoot/blob/main/gateware/dragonBoot/sim/spi.py#L24 fake platform, with fake resources for the sim

21:35 <d1b2> <dragonmux> https://github.com/shrine-maiden-heavy-industries/arachne/blob/main/arachne/core/sim.py#L47 constructing the Simulator object with the test bench + fake platform

21:35 <d1b2> <dragonmux> please note, Fragment is going to be replaced so this will break in a future version of Amaranth, but this works for right now

21:37 <d1b2> <dragonmux> hope that helps Guest41

21:40 <Guest41> TY d1b2 !
