Aldec facilitates FPGA design prototyping and prototype testing with its latest HES Proto-AXI software

22 January 2019

Aldec’s HES Proto-AXI 2018.12 provides a comprehensive FPGA prototyping environment with new HES boards support, Vivado board definitions, sample designs, and interrupt support in HES Proto-AXI interface.

HES Proto-AXI 2018.12 provides a comprehensive FPGA prototyping environment, with new HES boards support, Vivado board definitions, sample designs and interrupt support in HES Proto-AXI interface.

Aldec, a pioneer in mixed HDL language simulation and hardware-assisted verification for FPGA and ASIC designs, has unveiled the latest release of its HES Proto-AXI software package, serving as a Host-to-FPGA bridge in FPGA-based prototyping, as well as High Performance Computing (HPC) applications.

Release 2018.12 features new HES board HES-XCVU9P-ZU7EV support, including a comprehensive collection of FPGA prototyping resources, such as Vivado board definitions and sample designs. The other important component of the package, HES Proto-AXI module, now includes interrupt support and a Python API.

Board packages provided by the latest release facilitate the development of FPGA-based prototypes and their operating environments. Board definition files enable quick connection of designs to on-board peripherals in the Xilinx Vivado design environment. Moreover, sample projects contain complete source codes and can be used as starting points for the user’s applications. This greatly improves productivity, shortening the total time of the overall prototyping stage.

The new HES Proto-AXI provides a unique host interface, with AMBA AXI4 interconnect, that can be used to bridge the prototyped design to either a PC host (via PCIe interface) or a Xilinx Zynq/ARM Cortex embedded host. In addition, interrupts support is a new feature of HES Proto-AXI 2018.12. It allows for the replacement of register pooling with asynchronous interrupt events from hardware to software, thus enabling more robust test applications. The addition of a Python wrapper to HES Proto-AXI API further empowers rapid software development.

With such strong software support and a ready-to-use HES Proto-AXI Host Interface, Aldec HES boards can also be used as hardware accelerators for algorithms in HPC as well as High Frequency Trading (HFT) applications.

“The new release of HES Proto-AXI has been eagerly awaited by our customers, who always seek reliable prototyping resources, in addition to hardware products. Aldec hardware solutions always come with software support,” said Zibi Zalewski, General Manager of Aldec’s Hardware Division. “As engineers ourselves, we empathise with our users. We understand the technical and schedule pressure they are facing. We therefore developed our HES boards with the HES Proto-AXI software package, which contains reusable prototype building blocks, to accelerate prototype development.”

The new HES Proto-AXI 2018.12 software is available now. To learn more or to evaluate HES Proto-AXI, please visit, e-mail, call +1 (702) 990-4400, or contact one of Aldec’s worldwide distribution partners.
