Thanks for the support! I am using the latest SDx Hello, I had exact same problem, and finally I managed to solve it.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. The top-level directory structure shows the the major design components. To run the pre-built SD card imagefollow the instructions on 5. The platform include all the libs that needed. The following tutorials assume that the Vitis and XRT environment variable is set as given below.

Note that mpsoc common system should be downloaded in the 3. HWH file is a important file that need by the vai-c tool. The file has been created when compile by the Vitils tool. It works together with vai-c to support model compilation under various DPU configurations. If the user change the DPU settings. The model need to be created again.

The DPU IP provides some user-configurable parameters to optimize resource utilization and customize different features. There are also options for addition functions, such as channel augmentation, average pooling, depthwise convolution. The DPU core number is set 2 as default setting. The project will integrate 2 DPU. The user can delete this property, Then the project will integrate 1 DPU. Change the number 2 to others, The project will integrate DPU number as you want.

The default setting is B for ZCU You can get all the configurations form PG There are two options of RAM usage. The user can get more details in the chapter 5 in UG The user need modify the tcl for other numbers of DPU. Need to specify connectivity to the various ports in the system for the DPU. Refer the vitis document. Using the following comment to check the ports of platform. If the platform doesn't have enough port to connect the port of DPU.

The ports can share with other IPs. The related files need to be copied incuding the following path. It can be detelted. The relevant statement need to be deleted inthe makefile at the same time. If the user changes the directroy structure, the relative paths in the script files need to be modified. If you meet some timing issues. Otherwise, you'll see board hangs or reboot when running some models on ZCU board. We use optional third-party analytics cookies to understand how you use GitHub.

Its rather complex behavior as a tool, and the absence of a true file cleanup option require a method to create a compact set of files. Vivado has an option to archive an entire project, along with its dependencies into a single ZIP file, which is relocatable, and apparently intended for storing snapshots.

Vivado: Packaging for version control, distribution and repeatability

This page suggest an alternative, which is based upon Tcl scripting. This tool is still evolving, so there are significant differences even with respect to The minimal kit has to be crafted partially by hand: The necessary files are collected manually, and a Tcl script which regenerates the Vivado project from scratch is set up. A source control system only needs to track the Tcl script and a rather small set of source files, which are all mentioned in the Tcl script itself or related to as IPs.

The suggested flow starts with the script that Vivado produces, and turns it the main component of a self-contained kit by making simple changes to it. Alternatively, use the following Tcl command:. In a perfect world, this would have been enough. Unfortunately, this script creates a new project in a new location, but relying on the source files in their current, old, position. This is far away from an independent kit: The script will fail to run if the old project has been moved or removed, and even worse: If changes are made to the sources of the old project, they will take effect on the new one.

Nevertheless, the Tcl script is quite easily modified to be part of an self-contained bundle. Some of these files may be unnecessary for building the project, e. Naturally, these probably have no place in a compact package. The remote source files are given with their absolute paths, which reflects their current positions. XCI and BD files which define IP cores and block designs should be kept in separate directories which are populated by other files by Vivado.

This part sets up the variables containing paths to key directories. As mentioned before, the script assumes that the original project is in place, and a new project should be set up based upon it. A couple of remarks for Tcl newbies: Expressions that are enclosed with square brackets e.

This means that when the script is run, the source files are looked for in directories relative to where Vivado was run from, regardless of where the script itself resides. The intuitive place for everything to happen is relative to where the script resides. For example. The project is hence created in the same directory as the script. This part speaks for itself, more or less.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

New embedded platforms are supported on the Vitis software platform, and SDSoC platforms are now deprecated. The new DFX version of the platforms provides a shell where the kernel can be programmed without reimplementing the complete hardware design. For more information, visit the Vitis software platform web page.

This guide covers the following embedded vision reference platforms for the Vitis environment. These Vitis embedded platforms can be generated using sources. The pre-built platforms are also available if you wish to use them directly to build the accelerators.

The design with the Regulus ISP is not provided here due to licensing limitations; only the SD card image is available for evaluation.

View code. Releases No releases published. Packages 0 No packages published.Many of today's workloads and applications such as AI, data analytics, and live video transcoding, and genomic analytics, require an increasing amount of bandwidth. Traditional DDR memory solutions have not been able to keep up with the growing compute and memory bandwidth-intensive workloads are becoming data movement and access bottlenecks.

This figure shows the compute capacity growth vs traditional DDR bandwidth growth. High-bandwidth memory HBM helps alleviate this bottleneck by providing more storage capacity and data bandwidth using system in package SiP memory technology to stack DRAM chips vertically and using a wide bit interface.

These devices also include up to 2. The purpose of this article is to discuss what design aspects can negatively impact memory bandwidth, what options we have available to improve the bandwidth, and then one way to profile the HBM bandwidth to illustrate the trade-offs. Before discussing what impacts memory bandwidth let's explain how bandwidth is calculated.

Anyone who has worked with external DRAM interfaces knows achieving theoretical bandwidth is not possible.

In fact, depending on several different factors, it can be difficult to even come close. Here are several of the top contributing factors that can negatively impact your effective bandwidth. There are many advantages to having a hardened switch such as flexible addressing and reduction of design complexity and routing congestion. WP does a good job of highlighting many of the advantages if you're interested.

To enable flexible addressing across the entire HBM stacks the hardened AXI switch contains switch boxes broken up across 4 masters x 4 slaves. This facilitates the flexible addressing but there is a limitation that can impact memory bandwidth. There are only 4 horizontal paths available which depending on which AXI channel is access which addressable memory location in the HBM stack can greater limit your achievable bandwidth due to arbitration.

Now that we know what some of the contributing factors to poor memory bandwidth let's discuss some options available to mitigate them. Consider changing your command and addressing patterns. This will get you the biggest bang for your buck. For this test, read-only traffic is sent across all MC's. Then regenerate new. Note, that how the AXI Switch is configured can also impact the HBM bandwidth and throughput and should be considered profiling as well.

A future update to this article will provide profiling results from using various different MC options. This flow will be described later in the article. To profile the HBM bandwidth create or use an existing design or application. To profile different HBM configurations you will need access to the hardware design in order to modify the HBM IP core and then generate new bitstreams and new.

What is Vitis technology you ask? Vitis is a unified software tool that provides a framework for developing and delivering FPGA accelerated data center applications using standard programming languages and for creating software platforms targeting embedded processors. If you are targeting a custom platform, or even the U or VCU, and need to create a custom hardware platform design this can also be done. As workload algorithms evolve, reconfigurable hardware enables Alveo to adapt faster than fixed-function accelerator card product cycles.

Having the flexibility to customize and reconfigure the hardware gives Alveo a unique advantage over competition. In the context of this tutorial, we want to customize and generate several new hardware platforms using different HBM IP core configurations to profile the impacts on memory bandwidth to determine which provides the best results.

Using Microblaze as the traffic generator makes it easy to control the traffic pattern including memory address locations and we can use a default memory test template to modify and create loops and various patterns to help profile the HBM bandwidth effectively. The steps to build a design in the Vitis tool or SDK are similar and will include something like this:. The memory test template is a good starting point for generating traffic as it will run through all AXI channels enabled in your design and the HBM memory range and traffic patterns can be easily modified.
