Hello, I’m trying to model bidirectional I/O (at a low level) and I get the multiple drivers error or what I believe is incorrect resolution on ‘Z’. I’ve been googling for about a week and have not found anything that shows me how to model tri-state signal. In the spec, it states that I should use sc_signal_rv, but I don’t get the expected output. If I drive a ‘Z’ at one place and a ‘1’, I get ‘X’. If I drive a ‘Z’ from one driver, but a ‘0’ from the other, I get a ‘0’. I expect that there’s an obvious fix for this issue, but I’ve not been able to find it. Any suggestions? Thanks, Kevin |
