Aravalli Sainath Chaithanya, Myadari Radhika . Design and Functional Verification of a 1x4 Switch for Packet-Based Data Transmission. International Journal of Computer Applications. 186, 62 ( Jan 2025), 1-10. DOI=10.5120/ijca2025924434
Abstract
This work presents the design and functional verification of a 1x4 switch, a key component in packet-based communication protocols operating at the network layer of the TCP/IP model. The switch facilitates intelligent routing of data packets from a single input to multiple outputs, ensuring efficient and reliable communication. Addressing the growing need for robust verification in modern ASIC design—where verification consumes 60% of the design cycle and 90% of chip failures result from inadequate verification—this study develops a System Verilog-based verification environment. The design incorporates finite state machines (FSMs), FIFOs, and memory modules, with extensive simulation across diverse scenarios to validate functionality. State-of-the-art EDA tools, including Xilinx ISE 14.7 and Synopsys VCS 2021.09, are utilized for design synthesis and verification. This approach achieves comprehensive coverage, enhances reliability, and ensures reusability, making it a significant contribution to the field of network hardware design.
