General Description: When usind dc2ncf, this error is generated:
ERROR [#154]: Invalid argument -max for set_input_delay constraint at line x
Dc2ncf will generate a ncf file that does not contain the timing contraint specified at line x.
Dc2nf does not support the -max argument specified by Synposys timing constraints. Simply remove the -max argument from the timing constraints and run dc2ncf again.
This problem only exists in M1.3. In M1.4. Dc2ncf will ignore the -max argument but write out the ncf file with the timing constraint specified at line x. The -max option for set_input_delay/set_output_delay is not supported in M1.3 and M1.4. Currently, Xilinx only supports worst-case delays.
For more information about Synopsys timing constraints that are supported by dc2ncf, please refer to Section: Creating Timing Constraints, Chapter: 3, of the Synopsys XSI Interface/Tutorial Guide.
