Unconstrained input ports

WebTo constrain all the input paths in our design for setup time, in addition to the clock, we must provide the latest arrival time of the data at the input ports relative to the launching flip-flop’s clock edge (the time delay is called the input delay). WebVerilog Ports. Ports are a set of signals that act as inputs and outputs to a particular module and are the primary way of communicating with it. Think of a module as a fabricated chip …
