Note that users of clocking blocks already expect to be able to detect change events on an input clockvar. This is very, very similar to the detection of events on $past() or $sampled(). I have not been following this discussion as closely as I should, and I don't have much expertise to contribute to sv-ac, but I would urge you all to share this issue with sv-ec and sv-bc. I accept that it raises some tricky problems, but I think users will be mightily confused to find they can't detect changes on the result of $sampled() or $past(), where the user was expecting to get a deglitched and possibly delayed version of a signal and wanted to use changes on that conditioned signal to trigger downstream activity. -- Jonathan Bromley, Consultant DOULOS - Developing Design Know-how VHDL * Verilog * SystemC * e * Perl * Tcl/Tk * Project Services Doulos Ltd.
