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 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 ...

WebIf 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. The set_input_delay and set_output_delay constraints are typically used when connecting the FPGA to an external … WebAccurate timing analysis requires constraining all input and output ports. Follow these steps to identify unconstrained paths and apply input and output delay constraints to the ports. To identify unconstrained path in the design, double-click Report Unconstrained Paths the Diagnostic reports. rayus radiology the villages fl
