Udi Finkelstein	2b9c75f8e3	This PR should be the base for discussion, do not merge it yet! ... It correctly detects reg/wire mix and incorrect use on blocking,nonblocking assignments within blocks and assign statements. What it DOES'T do: Detect registers connected to output ports of instances. Where it FAILS: memorty nonblocking assignments causes spurious (I assume??) errors on yosys-generated "_ADDR", "_DATA", "EN" signals. You can test it with tests/simple/reg_wire_error.v (look inside for the comments to enable/disable specific lines)	2018-03-11 23:09:34 +02:00
