The Digilent Cmod module is a small, 48-pin DIP form factor board built around a Xilinx Artix 7 FPGA. The board also includes a USB-JTAG programming circuit, USB-UART bridge, clock source, Pmod host connector, SRAM, Quad SPI flash, and basic I/O devices. These components make it a formidable, albeit compact platform for digital logic circuits and MicroBlaze embedded softcore processor designs. An FPGA is a semiconductor device consisting of a matrix of Configurable Logic Blocks (CLBs) connected through programmable interconnects. The user determines these interconnections by programming SRAM. A CLB can be simple (AND, OR gates, etc) or complex (a block of RAM). The FPGA allows changes to be made to design even after the device is soldered into a PCB.
