| * | | deminout: prevent any constant assignment from demoting to inputMarcin Kościelnicki2020-03-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, ``` module top(inout io); assign io = 1'bx; endmodule ``` would have the `io` pin demoted to input (same happens for `1'bz`, but not for `1'b0` or `1'b1`), resulting in check failures later on. Part of fix for #1841.
