cycle counter

[David Peng]

Hi,

Do you have a built-in cycle counter?

Thanks,

David

Hi David,

Yes. The simulation pass adds a `sim_cycle_count` method that you can use to get the cycle count. You can see it in action here:

Best,

Chris

Hi, Chris,

This sim_cycle_count only exists in top sim component. How can a module component get the cycle count? 

Any suggestion?

Thanks,

David

Hi David,

There is no support for this out of the box ... you could either write your own PyMTL3 pass to instrument all PyMTL3 components with cycle counters or just implement your own inside any component.

Best,

Chris
