Designers frequently prototype new circuits using Field Programmable Gate Arrays (FPGAs). Depending on the application and providing the FPGAs do not become obsolete, this may provide an ideal solution for low volumes.

However, if the designer needs low unit cost, low power, high density and high performance, a digital ASIC will always win out. Perhaps surprisingly, the break-even point is often less than 1000 pieces. GE Aviation has conversion programmes for all major FPGA vendor devices.

With an ASIC solution, the screening level can be whatever the customer requires and the longevity can be guaranteed by holding the die (the lowest cost stage) for at least two decades.
