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. WebWWW.TESTBENCH.IN - Systemverilog Interface INTERFACE The communication between blocks of a digital system is a critical area. In Verilog, modules are connected using module ports. For large modules, this is not productive as it involves Manually connecting hundreds of ports may lead to errors. Detailed knowledge of all the port is required.

http://www.testbench.in/IF_01_INTERFACE.html WebSystemVerilog allows the module definition parametrized by certain values, which makes the modules more reusable. For instance, suppose we have an ALU module parametrized by the data width, we can reuse the same definition for both 32-bit and 64-bit ALU instantiation. by 60WebThe interface construct in SystemVerilog was specifically created to encapsulate the communication between blocks, allowing a smooth migration from abstract system-level design through successive refinement down to lower-level register-transfer and structural views of the design. cfop 1953
