01signal: Quartus: Packing registers into I/O cells
WebSo when you set the output delay (max) to 1.5ns you're saying Tsu + Te is 1.5ns, meaning the FPGA has Tclk - 1.5ns = 2.5ns to get your data from the output register to the FPGAs output pin. Which may be tight or may be trivial depending on the FPGA. What you aren't telling the tools is what the latency difference is between your two clocks.
