WebIf the input and output delays reference base clocks or PLL clocks rather than virtual … WebJun 10, 2024 · You can use the set_max_delay and set_min_delay instead. For e.g, if I really understood your requirement on ulpi_data: set_max_delay -from [get_registers *] -to [get_ports ulpi_data] 8.200 Where 8.200 is obtained as the timing window available: clock period - input delay + skew at destination flop: 16.600 − 6.00 + ( − 2.400) = 8.200 ns
WebThe set_output_delay constraint is not used to adjust a delay in order to make a path pass … WebFor I2O paths, the start point is input port whereas end points are output ports. One can assume input delay for input ports and output delay for output ports. Normally the combinatorial paths between inputs and output ports are constrained so that minimum and maximum delay constraints are met. Figure 8: Min/Max delay constraints for I2O paths ...
WebSpecifies that the delay value should be treated as the minimum delay. Required: No ¶ Specifies the delay value to be applied Required: Yes [get_ports {}] ¶ Specifies the port names or port name regex. Required: Yes Note If neither -min nor -max are specified the delay value is applied to both. set_clock_uncertainty ¶ WebJul 22, 2024 · if you are looking for set_input_delay & set_output_delay, then here is the answer: set_input_delay is sets input path delays on input ports relative to a clock edge. meaning, if you have. clock period = 10. input delay = 3. Thus, your data will be arrived after 3. Same thing happen when you set "set_output_delay".

Likewise, if an output doesn't work well, use the opposite clock edge on the output flip-flop. This way usually gets the electronics working quick and simple. how does a magnetic water conditioner workWebDec 7, 2004 · coming to the set_input_delay and set_output_delay part if the inputs and outputs in the top level are from the digital submodule, you can assign delay values depending on your time budget. but for ports coming from or going to analog sub module (or macro) you need not set input and output delays. istead, use set_false_path to eliminate … how does a malay mancatcher workWebIf you do not put a constraint (eg. set_input_delay, set_output_delay, create_clock, others) on a port then Vivado will ignore the port during timing analysis.
