systemverilog, how to handle reset?

The systemverilog semaphore is really half baked.

I could not find any way to release the semaphores in case of a reset, something like .flush() for uvm_tlm_fifo?

There is also no method to know how many semaphores are locked?

Is there some wrapper available in UVM something like uvm_event which extends the basic semaphore functionality?

People suggested me to use mailbox/tlm_fifo for more functionality, but i could not find an alternate to semaphore for allocating more than 1 keyCount.

If anyone has any suggestions please let me know.

Thanks in advance.

Solution

SystemVerilog's semaphore and mailbox are basic built-in classes that you can extend to suit your needs. Semaphores provide the basic key locking and unlocking mechanisms, but it is up to you to manage the keys.

What I meant was you can extend or encapsulate the semaphore to control who has access to the keys and how many keys are in use.
