A novel architecture called FLEX (flexible logic element matrix) has been designed which supports high logic densities up to 24,000 gates, maximizing overall system performance in a user design. This has been accomplished through a dual granularity approach and a global interconnect strategy. The dual granularity and global interconnect approach has succeeded in supporting both short nets and long nets for maximum performance.
