control knobs for a driver to be controlled from test class?

[swapnilm]

Dear All,

Is it always the case that the TOP test class can control/manage the control knobs of sequences only? I mean, I want to override/control some parameters of driver class from top test class, can this be done? If yes, how can that be done? because top test class stimulates only a sequence, so how would the control knob of driver be controlled from top test class? any guidance will be helpfull.

Thanks

Yes it can be done.

You can wrap the control knobs in a class and put it in the config_db.

There's lots of examples on the Verification Academy,
