The verification task of today’s multi-million gatesdesigns has become the primary bottleneck in the designflow. Industry estimates are that functional verificationtakes approximately 70% of the total effort on a project.Rising gate count combine with greater design complexityhas lead to much longer verification times. Time-to-marketschedules are much harder to meet while project costsincrease. According to a survey conducted by CollettInternational Research Inc. in 2002 [9], 60% of all tapeouts,that requires silicon re-spin, contained logic or functionalflaws. Among those faulty integrated circuits, 82% haddesign errors. Incorrect or incomplete specifications,corner cases simply not covered during verification orchanges in design specifications are a few causes of theseflaws.New verification techniques and methodologies arerequired to cut verification time and improve the quality ofverification. Hopefully, hardware verification languages(HVL) come to the rescue, raising the testbench at a higherabstraction level. With specific verification syntax andfaster simulation speed, HVLs improve performance andquality compared to RTL testbenches, thus reducing thetime spent in verification.In this work we focus our efforts toward theverification of digital signal processing (DSP) applications.Most signal processing designs begin with algorithmicmodeling in the MATLAB and Simulink environment.Therefore, we believe that hardware verification could besignificantly improved and accelerated by reusing thesehigh level golden references models.
