DIGILENT DIGIL 471-015 User guide

TheZyboZ7is a feature-rich, ready-to-use embedded software and digital circuit development board built around the
Xilinx Zynq-7000 family. The Zynq family is based on the Xilinx All Programmable System-on-Chip (AP SoC) architecture,
which tightly integrates a dual-core ARM Cortex-A9 processor with Xilinx 7-series Field Programmable Gate Array
(FPGA) logic. TheZyboZ7surrounds the Zynq with a rich set of multimedia and connectivity peripherals to create a
formidable single-board computer, even before considering the flexibility and power added by the FPGA. TheZyboZ7's
video-capable feature set, including a MIPI CSI-2 compatible Pcam connector, HDMI input, HDMI output, and high
DDR3L bandwidth, was chosen to make it an affordable solution for the high end embedded vision applications that
Xilinx FPGAs are popular for. Attaching additional hardware is made easy by theZyboZ7's Pmod connectors, allowing
access to Digilent's catalog of over 70 Pmod peripheral boards, including motor controllers, sensors, displays, and more.

TheZyboZ7is a direct replacement for the popularZybodevelopment board, which will soon be phased out of
production. The designs are very similar, however theZyboZ7adds several features and performance improvements. To
assist in migrating from theZyboto theZyboZ7, Digilent has created a migration guide, available on
theZyboZ7Resource Center.

TheZyboZ7can be purchased with either a Zynq-7010 or Zynq-7020 loaded. These twoZyboZ7product variants are
referred to as theZyboZ7-10 andZyboZ7-20, respectively. When Digilent documentation describes functionality that is
common to both of these variants, they are referred to collectively as the “ZyboZ7”. When describing something that is
only common to a specific variant, the variant will be explicitly called out by its name.

The primary difference between the two variants is the size of the FPGA inside the Zynq AP SoC. The Zynq processors
both have the same capabilities, but the -20 has about a 3 times larger internal FPGA than the -10. Also, The Zynq-7010
has slightly fewer FPGA attached pins than the Zynq-7020, which means several features found on theZyboZ7-20 are not
available on theZyboZ7-10. The differences between the two variants are summarized below:

Purchasing Options

TheZyboZ7-20 includes a heat sink in order to dissipate the extra heat generated from the additional FPGA resources
when running complex, fast-switching designs.

The board can be purchased stand-alone or with a voucher to unlock the Xilinx SDSoC toolset. The SDSoC voucher
unlocks a 1 year license that can be used with theZyboZ7. After the license expires, any version of SDSoC that was
released during this 1 year period can continue to be used indefinitely. For more information on purchasing, see
theZyboZ7Product Page. At the time of purchase, it is also possible to add-on a microSD card, 5V 2.5A power supply,
and micro USB cable as needed. A smallfan(ZyboZ7Fan Datasheet) that attaches to the heat sink can be added on to
theZyboZ7-20 too, however this fan will not work with theZyboZ7-10.

Note that due to the smaller FPGA in the Zynq-7010, it is not very well suited to be used in SDSoC for embedded vision
applications. We recommend people purchase theZyboZ7-20 if they are interested in these types of applications.

TheZyboZ7is fully compatible with Xilinx’s high-performance Vivado ® Design Suite. This tool set melds FPGA logic
design and embedded ARM software development into an easy to use, intuitive design flow. It can be used for designing
systems of any complexity, from a complete operating system running multiple server applications, down to a simple bare­metal program that controls some LEDs. It is also possible to treat the Zynq AP SoC as a standalone FPGA for those not
interested in using the processor in their design. TheZyboZ7is supported under Vivado's free WebPACK™ license,
which means the software is completely free to use, including the Logic Analyzer and High-level Synthesis (HLS) features.
The Logic Analyzer assists with debugging logic that is running in hardware, and the HLS tool allows you to compile C
code directly into HDL.

Design resources, example projects, and tutorials are available for download at theZyboZ7Resource Center.

Zynq platforms are well-suited to be embedded Linux targets, andZyboZ7is no exception. Digilent currently does not
provide a Petalinux example for this product, however one will be available in the near future on theZyboZ7Resource

Center.
