12.1 Constraints Editor - "WARNING:hi429/TNM_NET property is not supported for CPLDs"

説明

The following warning occurs in the fitting report: 

 

"WARNING:hi429 - Cannot apply TIMESPEC TS_CLOCK = PERIOD:CLOCK:20.000000 nS:HIGH:10.000000 nS because of one of the following: (a) a signal name was not found; (b) a signal was removed or renamed due to optimization; (c) there is no path between the FROM node and TO node in the TIMESPEC."

ソリューション

This warning occurs because the Constraints Editor writes out a TNM_NET property, but TNM_NET is not supported for CPLD designs.  

 

To work around this issue, change the TNM_NET property in the UCF file to "TNM" (delete the "_NET" portion).
