False Path settings in .qsf file

1,007 Views

Hello All,

I am using Altera Max700AE CPLD device for my design. In my design I have two clocks one with 45 Mhz and another with 4 Mhz.

1) I can not able to set setup and clock to out settings fro each clock

2) I want to exclude one path which I know it will not meet the timing as the synchronized outputs are used as input to some on nand gates and multiplexers to generate final output, I can not able to do exclusion of path (false paths)

I am using clasic timing analyser. Timequest anylser is not supported for this device.

And all my constraints are presented in .qsf file.

I have tried wih the command set_false_path.

I have tried set_timing_cut_assignment.

Can any body help me out in resolving this issue.

best regards,

Pavan M
