Eclypse Z7 Hardware Reference Manual

The Eclypse Z7 is a powerful prototyping platform, featuring Xilinx's Zynq-7000 APSoC.
Two SYZYGY interface connectors are featured, enabling high speed modular systems.

Eclypse is designed to enable high speed analog data capture and analysis right out of
the box. It is a platform for research and rapid prototyping of test and measurement
applications, potentially including software defined radio, ultrasound, other medical
devices, and much more. As a host board for

, applications for the Eclypse can

vary significantly between system configurations.

Petalinux is supported out of the box. Pre-built Linux images are accompanied by a
software API for bulk data transfer. This system allows new users to get started without
touching hardware until desired. The software supports a variety of common
programming languages, including Python, C/C++, and more. Digilent offers fully open
and customizable hardware designs, Linux images, and Linux software applications.
