Prohibit Location Constraints

• “PROHIBIT” Disallows the use of these sites within PAR:

  • CLBs, PADs, BUFTs, decoders, global buffer, function blocks/macrocells
  • single components (e.g. CLBs)
    CONFIG PROHIBIT=CLB_R1C5;
    
  • ranges of components (but not IOs)
    CONFIG PROHIBIT=CLB_R2C2:CLB_R4C6;
    
  • I/O constraint based on net name
    CONFIG PROHIBIT=P12;
    
    

Note: CONFIG PROHIBIT has specific limits depending upon the device. Please reference the “Libraries Guide” for these limits.
