SW-8.1i Spartan-3E PAR - "WARNING:Route:447 - CLK Net:XYZ may have excessive skew because ### CLK pins failed to route using a CLK template."

描述


PAR successfully routed my design, but the PAR report file (.par) contains warning messages about clock skew. What is the problem?



"WARNING:Route:447 - CLK Net:XYZ may have excessive skew because

### CLK pins failed to route using a CLK template."

解决方案

In some cases prior to ISE revision 9.1i, this clock skew warning was issued as a false warning. You can safely ignore the warning message if the Clock Report in the .par file does not report any skew problems for the clock net listed in the message.
