Help: SV Function/Task Definition Accepting Arbitrary Sized Vector Input

yushu81

Hi EETOP Buddies,

I’d like to define some SystemVerilog tasks/functions which can accept arbitrary sized vector input, like system function $onehot and $countones.

But I don’t know how to declare the argument in task/function, or use PLI to realize it.

Pls. kindly provide your solution if you have such experience.

Thanks a lot.

Try use Dynamic Arrays or Queues as the argument in task/function
e.g.
    virtual protected task my_task(int data_in[$], data_out[]);
