WebNov 4, 2016 · The maximum value of t_output_delay (1.4 ns) is simply used for setup time and the minimum value (1.0 ns) is used for hold time. Let's think about setup time. OUT1 has to transit 1.4 ns before (or earlier) the falling edge of CLK2. Say your clock period is 10 ns and the source register is also negedge triggered. WebDec 27, 2024 · min output delay = -device tH_DEV + sum of all min buffer delays on data path - sum of all max buffer delays on clock path Input constraints Input data signals can …
WebAs with the calculation for set_output_delay -max, the data path continues the clock path until the output is stable. This is calculated to happen at 3.826 ns (note the difference with the slow model). ... This demonstrates why the number that is used with set_output_delay -min is the hold time, that is specified for the input of the external ... WebThe set_max_delay and set_min_delay commands specify that the maximum and minimum respectively, required delay for any start point in to any …

WebJul 10, 2024 · For such applications, the recommended method for Libero is to use min and max delays as shown below: · Rise-to-fall and fall-to-rise. The other paths (rise-to-rise and fall-to-fall) are invalid. No constraints are needed for these launch-capture applications. Output path constraints python api meansWebThis analysis starts in "Data Arrival Path" with setting the input port (test_in) at 2 ns, as specified in the min input delay constraint, and continues that data path. Together with the FPGA’s own data path delay (3.057 ns), the total data path delay stands at 5.057 ns. The clock path is then calculated in "Data Required Path", starting from ... python api key 생성WebTCQ + comb_delay (min) + output_delay > min_delay (required) For 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.

On a simple level, that means the FPGA needs to get it's data out within 6ns so that, after the external 4ns delay is added, it can be captured by the latch edge at time 10ns. Now, where does that 4ns come from? python api python
