IF_A_1 = IF_A_2 ). So an instantiated interface cannot be connected to an interface defined in the module port list without doing the connection by hand, one variable/wire at a time.

WebFeb 16, 2024 · SystemVerilog interfaces were developed to allow for easier connectivity between hierarchies in your design. One way to think of them is as collections of pins that are common to many modules. Instead of having to define many pins on each module, they are defined once in an interface, and then the interface is defined on the module instead … WebAug 21, 2024 · In SystemVerilog, a bundle of wires is called an interface.
