On Arria10 there are 6 transceivers in a single bank. If more than 6 transceivers are used these will end up in multiple banks. The ATX PLL can directly connect to the transceivers in the same bank through the 1x clock network. To connect to transceivers in another bank it has to go through a master clock generation block (MCGB) and the xN clock network. Add support for instantiating the MCGB if more than 6 lanes are used. In this case the first 6 transceivers will still have a direct connection to the PLL while all other transceivers will be clocked by the MCGB. Note that this requires that the first 6 transceivers are all in the same bank. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> |

HDL Reference Designs
Analog Devices Inc. HDL libraries and projects.
Getting started
This repository supports reference designs for different Analog Devices boards based on Intel and Xilinx FPGA development boards or standalone.
Prerequisites
or
Please make sure that you have the required tool version.
How to build a project
For building a projects, you have to use the GNU Make tool. If you're a Windows user please checkout this page, to see how you can install this tool.
To build a project, checkout the latest release, after that just cd to the project that you want to build and run make:
[~]cd projects/fmcomms2/zc706
[~]make
A more comprehensive build guide can be found under the following link: https://wiki.analog.com/resources/fpga/docs/build
Software
In general all the projects have no-OS (baremetal) and a Linux support. See no-OS or Linux for more information.
Which branch should I use?
-
If you want to use the most stable code base, always use the latest release branch.
-
If you want to use the greatest and latest, check out the master branch.
