6.2is3 CPLDFit - When a pad-specific OFFSET constraint is placed on a bidirectional port, warnings occur in the fitter report

説明


General Description: 
When a pin-specific OFFSET constraint is placed on a bidirectional port, the following warning occurs in the fitter report. 
 
"WARNING:Cpld:1151 - Cannot locate data input pad for OFFSET timespec 
'IN:44.000nS:BEFORE:CLK', the timespec is ignored."

ソリューション


This is a known issue and will be fixed in a future release of software. 
 
To work around this issue, create a global OFFSET constraint and then use specific OFFSET constraints if necessary for other non-bidirectional pads.
