WebMay 31, 2024 · Create clock: Syntax: create_clock ... Input delay defines the time requirements of an input port with respect to clock edge. Input ports are assumed to have zero input delay if it is not specified. The delay value to be specified is the delay between the start point and the object on which set_input_delay is being set relative to the clock edge. WebJun 20, 2024 · Set clock to 1, evaluate to create positive edge, and then set inputs / check outputs before dumping and incrementing sim time. On the next positive clock edge inside the while() loop, the inputs set previously will propagate into the design during eval, and then right after eval the inputs should be reset to their default values.
