Ignoring Paths (TIG) 

• Never changing input signal

  NET CHIP_MODE TIG;
  

• Ignore a signal for a specific timespec

  NET SLOW_SIG TIG=TS_01;
  

• Ignore false paths between registers

  TIMESPEC TS_TIG1=FROM:FFS(REGA*):TO:FFS(REGB*):TIG;
  
  Note: May have to use INST to create groups for synthesis designs.
