System development using Actel field programmable gate arrays

A new way to reduce risk and time in system-level development while retaining a high level of logic integration lies in the use of field-programmable gate arrays (FPGAs). An FPGA is an application-specific IC (ASIC) that is configurable by the designer at his or her desk. FPGAs are one-time programmable devices that are developed using a standard computer-aided-engineering (CAE) system and Actel software. As in any technology, a design is captured and functionality simulated. After the net list is translated and package pins assigned, the design must be mapped to the physical device and a file for programming the device must be created. The use of FPGAs provides benefits during all the stages of development. During prototyping the devices provide working hardware rapidly without the cost and delay of wire-wrapped standard device technology, whether for a prototype or emulation of masked gate arrays. Software development can begin as soon as a device is programmed. The design of a simple microprocessor-based computer system is considered as an example of how FPGAs can be used throughout the development cycle.<>
