There aren't examples about AxiSlave, AxiLiteSlave, or from_entity about cocotbext-axi HOT 1 OPEN

There are basically two ways to use AxiSlave and AxiLiteSlave. One way is to extend from it and override _read and _write, see AxiRam and AxiLiteRam. The other way is to specify a target, for that see the readme and https://github.com/corundum/corundum/blob/master/fpga/common/tb/mqnic_core_axi/test_mqnic_core_axi.py . I don't have any examples of from_entity as this is more for things like SV interfaces, and I don't really use SV at the moment. However, I think it would make a lot of sense to add some additional test cases for things like SV interfaces as I have had people ask about several variations of those. That's on my to-do list, but probably won't happen for a while.
