General Description: Why does Xilinx support equivalency checking?
Solution
1
With device size and design complexity both increasing, functional simulation is becoming very time-consuming for both testbench generation and simulation run-time. Formal verification is attractive because of its short run-time and complete functional coverage.
In addition, formal verification is a proven technology in the ASIC design environment. As more ASIC designers begin to design with FPGAs, formal verification is becoming an increasingly important flow for design.
