  What is fueling the popularity of FPGA technology to the point that it’s now replacing both gate array and standard-cell ASICsin many applications?A unique combination of accelerating product cycles,needs for higher integration than is possible in a gate array,fast migration to deep submicron process technology,and the explosion of networked applications are the keys.
  Re-programmability is the driver, allowing designers to take greater risks and innovate more during the development phases without losing time to market. It also forgives changing standards or last-minute feature changes, and enables true in-system reconfigurability. This lets telecom developers use one chip for many applications, rather than a separate ASIC for each specific custom requirement. One example comes from a set-top-boxmaker who discovered that one FPGA could replace three ASICs, each one geared toward the custom specifications of Asia, Europe, and North America.
