WebDec 21, 2010 · The fpga's tool to do that is by inserting delays between io register and pins to reconfigure its own tSU/tH for inputs and its tCO for outputs. Thus the fpga is a device with user configurable tSU/tH/tCO unlike most ASICs. If you look at the diagram in the link, you will see a cloud between io register and the output data pin. WebInput Setup and Hold times (Tsu, Th) and Clock-to-Output times (Tco) are reported.
