Hi
I am new to fpga and i am using microzed board to simply light an LED. But i found that the clock is given from the PS to PL. In that case what should i do as i can't name the pin in the user constraint for the pin. Can anyone please help me.

Hi,

In fact, it is possible to nail down the relevant clock pin in the timing constraints by defining the pin of the PS block's instance.

However this is usually not necessary. I suggest implementing the design without creating a constraint for the clock that arrives from the PS. Then look in the timing report for a constraint that seems to be related. Chances are that a constraint that is generated automatically by the tools will do the job for you.
