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.

WebA logic option that implements an output register in an I/O cell that has a fast, direct connection to an I/O pin. Turning on the Fast Output Register option can help maximize … WebThose are set and clear registers. Which means you don't have to mask things. Instead of grabbing the current value, masking a bit in or out, and then writing it back, you can use those: GPIO_REG_WRITE (GPIO_OUT_W1TS_ADDRESS, 0x1); This will set GPIO0 high, and not affect any other bits.

WebThe clock-to-output timing is exactly the same as a plain output register that is packed into the I/O cell, but the delay on the input path is actually worse with the instantiation … WebUse "fast_output_register = on" to put a register that is storing a value that drives an I/O cell (either the data port or the OE port) into the I/O cell. You can set these attributes either on registers or on I/O cells. So if you have a bidirectional I/O, and want both the input path and output path

WebDec 16, 2024 · it's a very short path from the external input clock to the output flops. It's done by design to improve IO performance. don't confuse electronic delay and jitter.
