NanoTime Warning(DELC-004)
Hello everyone. Can anybody who is familiar with the Nanotime STA tool help me?
here is the information after trace-path:
Warning:Simulator Warning: Net DATA failed to switch.(DELC-004)
Warning:Failed to get delay from pin xxx (net DATA) edge rising to pin xxx (net DATA) edge rising ,unable to trace further.(DELC-003)
.......
there is no timing reports.
ps : the schematic is simple--only a latch comprised of CLK,DATA,DATAOUT. the mark_latch and match_topology is success.
Thanks!
