multicycle start
To set a multicycle maximum path, you can either move the end clock forward or the start clock backward. To set a multicycle minimum path, you can either move the end clock backward or the start clock forward. ,Reference clock (-start, -end):. Specifies whether the multicycle value is based on the source or destination clock waveform. Start (launch clock)( -start )— ...
