The Xilinx FPGA Test Patterns offered by Polybus provide an extensive suite of over 400 testing configurations designed to verify and enhance the functionality of Xilinx FPGAs. These patterns test the internal logic and interconnect integrity, helping to identify defects arising from handling or during system upgrades. Catering to the diverse architectures of numerous Xilinx FPGA models, these patterns support rigorous in-system testing and provide a safety net against defective components reaching operational stages. Through these tests, Polybus helps ensure that only the most reliable FPGA configurations are deployed, contributing to the enhancement of system reliability and performance.
