Figure out if the cocotbext-pcie library can be used to test litepcie? #47

Just recently found PCI express simulation framework for Cocotb. I wonder if it makes any sense to try and use this to help verify LitePCIe?

This could indeed be useful to test the core against another model but we should probably first improve the unit-tests of the core (as we did recently with LiteDRAM for example). Better unit-tests would allow doing simplifications/cleanups to the core (for example https://github.com/enjoy-digital/litepcie/commit/64d1f76304bc53b2b0109163433c5518c9a48731) that are difficult to do with confidence now.
