No. The whole point of the DCFIFO is to take care of the synchronization for you.

so, the flow will be like this :

--> 4 flits (16 bits each) send to router

NA domain(100Mhz) Router domain (200Mhz)

data_in[16bit][3:0] ---------> data_out[16bit][3:0]

signals & data synchronization process is taken care by DCFIFO.

correct?

thanks Guru..:)
