Fix AXI4 to AHB converter issues #141

Closed mkurc-ant closed 7 months ago

mkurc-ant commented 7 months ago

This PR fixes incorrect operation of axi4_to_ahb converter module where rvalid and bvalid depend on rready and bready respectively which is forbidden by the spec.

Microarchitectural tests are updated to exercise correct AXI channel handshaking. A VeeR configuration with AHB bus where the axi4_to_ahb module is used is added to CI regression tests.
