What can cause: Internal Error: Non-cutable edge forms a loop
|Assignee:||Wilson Snyder||% Done:|
I've verilated my design using options: -Wno-WIDTH -Wno-CASEINCOMPLETE -Wno-CASEX -Wno-MULTIDRIVEN If ignoring those warnings may cause "Internal Error" occuring first of all errors?

This is caused by the following in the memory wrappers
always @(posedge x) begin ... x = 0; end
This isn't synthesizable and is confusing the ordering code. I thought I would be able to have a fix by now, but it's elusive, so I think this will have to remain unsupported (though with a better error message.)
