February 7, 2007 -- Over the past 18 months, there has been a growing adoption of the use of FPGAs to prototype ASICs as part of an ASIC verification methodology. With the development costs for ASICs skyrocketing – a typical 90nm ASIC/SoC design tape-out today costs around $20M; a 90nm mask set alone costs over $1M; and total development cost for a 45nm SoC is expected to top $40M – it is clear to see why avoiding a respin by prototyping with FPGAs is attractive.
Besides the increase in mask set cost, total development cost is also increasing due to the reduced probability of getting the design right the first time. As design complexity continues to increase, surveys have shown that only about a third of today's SoC designs are bug-free in first silicon, and nearly half of all re-spins are reported as being caused by functional logic error. As a result, verification managers are now exploring ways to strengthen their functional verification methodologies.
