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 (http://store.digilentinc.com/). 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 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 bare-metal 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
(https://reference.digilentinc.com/reference/programmable-logic/zybo-z7/start).
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
(https://reference.digilentinc.com/reference/programmable-logic/zybo-z7/start).
The Zybo Z7 can also be used in Xilinx's SDSoC environment, which allows you to design FPGA accelerated programs and video pipelines
with ease in an entirely C/C++ environment. For more information on SDSoC, see the Xilinx SDSoC Site
(https://www.xilinx.com/products/design-tools/software-zone/sdsoc.html). Digilent will be releasing a video capable platform with Linux and
OpenCV support in the near future. Note that due to the smaller FPGA in the Zybo Z7-10, only very basic video processing demos will be
included with that platform. Digilent recommends the Zybo Z7-20 for those interested in video processing.
Those familiar with the older Xilinx ISE/EDK toolsets from before Vivado was released can also choose to use the Zybo Z7 in that tool
set. Digilent does not provide materials to support this, but you can always ask for help on the Digilent Forum
(https://forum.digilentinc.com).
