Put more amphasis on net names to resolve ambiguities The problem was that with the floating test case, the ambiguity resolution sometimes assigned the wrong pins and floating pins/connected pins were swapped. One option is to make the ambiguity resolver consider the pin connection state when tenatively evaluating nodes. Another option is to put more emphasis on net names and use them for ambiguity resolution. This has helped here.
