When I am running Spectre, I got "*Error* fprintf/sprintf: format spec. incompatible with data - nil"
How can i get rid of it?
Unfortunately it could be virtually anything.It essentially indicates an untrapped error condition - what's happening is that somewhere in the code it's doing something like:printf("blah %s blah\n" myVar) and myVar is nil rather than a string as expected. Since fprintf/printf/sprintf is used all over the place, it could happen any time a call to any of these functions happens with an argument that doesn't match the expected type - probably because something unexpected went wrong. This could be in some custom code or in the Cadence code - it could be anywhere.To narrow it down a bit, perhaps you could enter in the CIW:_stacktrace=20tracelevel=20tracelength=20and then reproduce the problem - and post the lines around problem from your CDS.log file - including what you were doing at the time, and all the stacktrace, etc...Probably best to deal with this through customer support really, but I can try to help you here too.Regards,Andrew.
