Introduction to Digital Design Using Digilent FPGA Boards

These devices are called field programmable gate arrays (FPGAs). The device consists of an array of configurable logic blocks (CLBs) surrounded by an array of I/O blocks. The Spartan-3E from Xilinx also contains some blocks of RAM, 18 x 18 multipliers, as well as Digital Clock Manager (DCM) blocks. These DCMs are used to eliminate clock
