Test Methods for Antifuse-Based FPGAs
-
Abstract
The classic architecture of antifuse-based FPGAs was described. Then the details about programmable logic module (PLM), placement and routing, programmable interconnection of antifuse-based FPGAs was presented. According to the test patterns of antifuse-based FPGA, a method for antifuse-based FPGA test, which combined ATE and mounting plate, was proposed. The results of the test experiments showed that the employed method can achieve successful test and confirmation of unprogrammed device at the factory.
