March 28, 2006 -- FPGAs are a valuable technology for designing and prototyping digital logic into medium-volume, medium-density applications. Their high unit cost, however, makes an FPGA cost-prohibitive to move into production. Several alternatives exist for taking a digital design implemented with an FPGA into production, including Structured ASICs, cell-based ICs, and gate arrays, all of which offer lower cost, higher performance, lower power consumption, and time-to-market advantages. While the thought of migrating an FPGA design into an ASIC can be overwhelming to a design team, teaming with an experienced ASIC vendor can help ease the process.

Designing a new product in an FPGA allows for design modifications to be made quickly in hardware. Once the design code is stable and the product is ready for production, a migration from an FPGA to a mid range ASIC can cut the production unit cost by one tenth. The low non-recurring engineering (NRE) charges associated with a mid-range ASIC solution coupled with a much lower unit cost make this strategy a powerful tool in achieving low overall costs, giving users a competitive cost advantage in the market.
