sc_signal_rv is the correct approach. You probably need to post your code here if you want help.

Subject: [systemc-forum] Modeling tri-state signal


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?
