*	flatten, techmap: don't canonicalize tpl driven bits via sigmap.	whitequark	2020-08-26	1	-0/+11
	For connection `assign a = b;`, `sigmap(a)` returns `b`. This is exactly the opposite of the desired canonicalization for driven bits. Consider the following code: module foo(inout a, b); assign a = b; endmodule module bar(output c); foo f(c, 1'b0); endmodule Before this commit, the inout ports would be swapped after flattening (and cause a crash while attempting to drive a constant value). This issue was introduced in 9f772eb9. Fixes #2183.
