HMCAD1520-FMC-EVB HDL project

Overview

The HMCAD1520-EBZ HDL design supports the following HMCAD1520 features:

• Single/Dual/Quad Channel modes

• 8/12/14 bit resolution configurations

• Sampling rates between 105 - 1000 MSPS

The HMCAD1520-EBZ evaluation board was designed for use with the Digilent ZedBoard via the field programmable gate array(FPGA) mezzanine card (FMC) connector.

Supported boards

• HMCAD1511-EBZ

• HMCAD1520-EBZ

Supported devices

• HMCAD1511

• HMCAD1520

• ADN4661

• ADM7154

• MAX3013

• LTC6419

• LTM8078

Supported carriers

CPU/Memory interconnects addresses

The addresses are dependent on the architecture of the FPGA, having an offset added to the base address from HDL (see more at CPU/Memory interconnects addresses).

Building the HDL project

The design is built upon ADI’s generic HDL reference design framework. ADI distributes the bit/elf files of these projects as part of the ADI Kuiper Linux. If you want to build the sources, ADI makes them available on the HDL repository. To get the source you must clone the HDL repository, and then build the project as follows:

Linux/Cygwin/WSL

Example of building the project with make

~$

cd hdl/projects/hmcad1520/zed

~/hdl/projects/hmcad1520/zed$

make

A more comprehensive build guide can be found in the Build an HDL project user guide.

Support

Analog Devices, Inc. will provide limited online support for anyone using the reference design with ADI components via the EngineerZone FPGA reference designs forum.

For questions regarding the ADI Linux device drivers, device trees, etc. from our Linux GitHub repository, the team will offer support on the EngineerZone Linux software drivers forum.

For questions concerning the ADI No-OS drivers, from our No-OS GitHub repository, the team will offer support on the EngineerZone microcontroller No-OS drivers forum.

It should be noted, that the older the tools’ versions and release branches are, the lower the chances to receive support from ADI engineers.
