Zmods

The Zmod™ family is Digilent's line of peripheral modules that conform to Opal Kelly's SYZYGY specification. Zmods are interface boards that offer modular high-speed I/O capabilities to compatible FPGA host boards.

Software Support

All Digilent Zmods are supported by custom controllers targeting 7-Series FPGA fabric, provided as IP for Xilinx's Vivado development environment. Check out the Zmods' resource centers, linked below, for more information.

Digilent provides software libraries for interacting with some Zmods, documented in the Zmod Base Library User Guide.
