Abstract :
Plessey Semiconductors Ltd. have recently introduced a novel type of Programmable Logic Device categorised as Field Programmable Gate Arrays (FPGAs). Offering exciting opportunities for FPGA applications, the devices are known as Electrically Reconfigurable Arrays-ERAs. ERAs allow the user to design and programme devices in their own premises resulting in short design and production lead times with no NRE charges. These features make the devices viable for small production runs and the natural choice of technology where frequent production variations are required to meet specific customer needs
