Do we need to use two monitors one each for input and output

[Khushi]

In UVM verification env, do we need to use two monitor if I want to sample the input (to DUT)and output(from DUT) and compare them in scoreboard.

In this case do I need to use two monitor, one on input and other on output ?

Can a single monitor does the same job ?

I tried but what I see by the time output arrives the input changes(for next set of inputs)

Thanks

you can use the one monitor for the dut input and output. And i think the root case is not base on how mant input/ouput of dut you have, but the interface type the dut have.

for exanple, if you have one axi input and one aix output, you can use one monitor to collect all input/outout axi transaction.

So i think the number monitor is based on the types of interfaces.
