Dear Javier, The delay is mostly always in clock cycles. It is assumed your design is running at some optimum clock frequency, so everything should be referenced to clock cycles.
BRAM latency = 1) the number of clock cycles taken for the data to be stored into the RAM after a write signal is asserted or 2) the number of clock cycles taken for the data to appear at the output of the BRAM after a read is asserted. There is often an input register stage and output register stage that add to this latency. If you are using the BRAM configured as a dual port RAM then you will mostly likely have a diferent write and read clock. The BRAM will often need a few clock cycles to synchronise to different clock domains. The same for a FIFO. If you want to align a specific data signal (A) with another signal (B) that is lagging then normally inserting a delay block (with the required delay in clock cycles) after the specific data signal (A) will work. You can determine the delays by simulating your design. I hope this helps.
