Abstract :
The Act-2 family of CMOS field-programmable gate arrays (FPGAs) uses an electrically programmable antifuse and novel architectural and circuit features to obtain higher logic densities while increasing speed and routability. Improvements include: two new logic modules, novel I/O and clock driver circuitry, and more flexible and faster routing paths. New addressing circuitry shortens programming time and speeds complete testing for shorts, opens, and stuck-at faults. Fully automatic placement and complete routing are retrained. Special software tools used for architectural exploration and layout generation are discussed
