WebApr 18, 2024 · In SystemVerilog, a bundle of wires is called an interface. An interface contains wires and synthesizable methods to perform operations such as sending and receiving transactions. An interface is RTL, just like your design. Here is an interface with 7 signals and a task to receive a transaction. interface color_ifc; logic r,o,y,g,b,i,v; WebJun 4, 2024 · I am looking for a clean solution to connect interfaces (and thereby monitors) to internal modules of a DUT. My env looks close to this - 1. An instance of DUT (dut_inst) has multiple sub-blocks within it. Let's say we have one such block - blk_a. 2. Let us say blk_a has 3 ports - inputs port1 and port2; output port3. 3.
