I am trying to create a generated clock whose frequency is a fractional multiplier to its source:
This constraint causes the following error:
How can I resolve this error?
Allowable values for the -mutiply_by and -divide_by parameters are integers.
To obtain a fractional output you would need to find the ratio of whole numbers which provide the desired fractional output.
In the case above, you would need to use a -mutiply_by value of 13 and -divide_by value of 12 to obtain the desired output.
For more information, please refer to the help information of the create_generated_clock command or UG835.
