A set_input_delay

WebInput Delay Constraints You can use a maximum skew specification to calculate input delay values. The maximum skew specification indicates the allowable time variation for individual bits of a data bus to arrive at the FPGA. The value of the input maximum delay is maximum skew value. The value of the input minimum delay is -maximum skew value. Web7 nov 2024 · In general, input delay (a.k.a. input latency) happens because the browser's main thread is busy doing something else, so it can't (yet) respond to the user. One common reason this might happen is the browser is busy parsing and executing a large JavaScript file loaded by your app.
