Multiport Router: Design and Verification for On-Chip Applications

The integration of several processing resources onto a single chip results from advancements in VLSI technology. The design adopts packet-switched networks with layered protocols and on-chip routers, connections, and network interfaces structured in a predefined topology. The performance depends exclusively on the routing. The device that transmits packets of data is designated as a router. This protocol intends to transmit data to its destination accurately. As a result, it permits appropriate data transmission over the channel. As a vital component of the architecture, the router has been ingeniously designed to enable the implementation of a competitive NoC architecture using Verilog Hardware Descriptive Language. The population’s growing need has driven several investigations and innovations in science and technology. It also impacted the VLSI system, as more transistors were packed into a single chip to meet these criteria, making the IC’s more complicated. The more sophisticated a chip is, the more energy and time it takes to test the design. Consequently, between 50 and 80% of the chip development is typically required for verification tasks. Verification requires a range of steps to be taken, commencing with the creation of the verification plan and concluding with the test bench’s test case development. Verifying the IP block through the coverage flow is an essential step after the test cases have begun to execute. The latest verification methodology (Universal Verification methodology) and the Hardware Verification Language (System Verilog) are used to validate the seven-port IP router’s operation.
