Lars-Peter Clausen ec8db3ee5b util_dacfifo: Reduce logic on high fan-out dma_wren_s signal 
The DMAC implementation guarantees that the expression `dma_valid &
dma_xfer_req` is always identical to just dma_valid.

When generating the util_dacfifo dma_wren_s signal the optimizer doesn't know
of this though and hence will route both signals into the LUT that drives
the write enable for the BRAMs.

Simplify the expression by removing dma_xfer_req from it. Considering this
can be a fairly high fan-out net and is typically the bottleneck for the
util_dacfifo timing this helps to improve the timing.

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.
