Async Fifo

UVM

Is it possible to get FIFO full condition in asynchronous FIFO if I am not enabling the write_en signal? In my RTL code write pointer and read pointer are internal signals and for the wrap-around condition for comparing FIFO full & FIFO empty we have internal signals.

I have made one interface & 2 agents one for reading & one for writing. I am running the read_test only where write_en == 0.

Is It necessary to write first into FIFO then read?

In reply to yask_kush:

If you do not enable the write nothing will be written. What will you read if you did not write anything to the fifo?

Looks like you got a nice interview question.
Ofcourse you can force the fifo full flag without writing anything to the fifo
