Hello,
I'm not TQ expert, so I have some simple questions - how to constrain internal memory in fpga? Esp. dual-port RAM with different rd/wr clocks? Can single-port memory be constrained with "set_multicycle_path"? brLink Copied

an Altera Dual Clock FIFO will already have a set_false_path between the two domains
we'll need more information to see if a multicycle is the right solution for your single port RAM- Mark as New

I have a ROM memory with internally registered data output, so it takes 2 clocks to read. Because of this output register in path I'm not sure about using 'multicycle' in this case. Is there need to constrain the memory anyway?

No. Just constrain the clocks and the memory will be constrained from that.
