Reference Design is only usable with the specified Vivado/SDK/PetaLinux/SDx version. Do never use different Versions of Xilinx Software for the same Project.

Basic Reference Design and SDSoC Platform projects for Win OS are available on:

Create SDSoC Platform Project

Trenz Electronic provides a tcl based built environment based on Xilinx Design Flow.

See also:

This cheaper describes how you can create SDSoC platform project from special Trenz Electronik Vivado projects.

This chapter is optional: Prebuilt SDSoC platform projects for Win OS are also available on the download area.

Vivado SDSoc Platform export

  1. Download and unpack package (use short path or 'subst' command to make path as short as possible).
  2. Run '_create_win_setup.cmd' script and choose option '1'
  3. Edit file 'design_basic_settings.cmd' and fill correctly all variables, set ENABLE_SDSOC=1. 
  4. Launch Vivado by command 'vivado_create_project_guimode.cmd'
  5. In Vivado: 
    1. run script in TCL console
      TE::hw_build_design -export_prebuilt
  6. (Optional) Build Petalinux:
    1. Copy OS folder from downloaded package to Linux PC.
    2. Copy hdf file located in prebuilt/hardware/<shortname> subfolder to Linux PC
    3. Switch to Linux PC and run in terminal:
      1. Initialize Petalinux SDK:
        source <petalinux_SDK_install_path>/
      2. Use hdf file to configure linux project:
        petalinux-config -p <path_to_petalinux_project> --get-hw-description
      3. Build petalinux image from within the project:
      4. Repeat previous step until images are sucessfully created. It may take from 1 to 5 attempts.
      5. Find linux images and copy them back to the Trenz package
        Files to be copied are located in <petalinux_project_path>/images/linux. Filenames are:
        image.ub, u-boot.elf, bl31.elf
        Target folder in Trenz package is:
        prebuilt/os/petalinux/default for all 1GB DDR modules.
        prebuilt/os/petalinux/<shortname> for both supported 2GB DDR modules
      6. Return back to Vivado
  7. In Vivado:
    1. run script in TCL console
    2. run script in TCL console
  8. Custom platform for SDx tool is now exported to SDSoC_PFM folder sitting next to Trenz package folder

SDK/HSI Application

Source location: \sw_lib\sw_apps


TE modified 2018.2 FSBL


  • Si5338 Configuration, ETH+OTG Reset over GPIO
    • see xfsbl_board.c, xfsbl_board.h, xfsbl_main.c
    • Add register_map.h, si5338.c, si5338.h

Note: Remove compiler flags "-Os -flto -ffat-lto-objects" on 2018.2 SDK to generate FSBL



  • Set FSBL Boot Mode to JTAG
  • Disable Memory initialisation
  • see  xfsbl_initialisation.c, xfsbl_hw.h, xfsbl_handoff.c, xfsbl_main.c

Note:  Remove compiler flags "-Os -flto -ffat-lto-objects" on 2018.2 SDK to generate FSBL

Use SDSoC Platform Project

Included Example

Array partitionThis example shows how to use array partitioning to improve performance of a hardware function

Burst rw

This is simple example of using AXI4-master interface for burst read and write

Custom data type

This is a simple example of RGB to HSV conversion to demonstrate Custom Data Type usage in hardware accelerator. Xilinx HLS compiler supports custom data type to operate within the hardware function and also it acts as a memory interface between PL to DDR

Data access random

This is a simple example of matrix multiplication (Row x Col) to demonstrate random data access pattern

Dependence inter

This is a simple example to demonstrate inter dependence attribute. Using inter dependence attribute user can provide additional dependency details to compiler which allow compiler to perform unrolling/pipelining to get better performance.

Direct connect

This is a simple example of matrix multiplication with matrix addition (Out = (A x B) + C) to demonstrate direct connection which helps to achieve increasing in system parallelism and concurrency

Dma sg

This example demonstrates how to use Scatter-Gather DMAs for data transfer to/from hardware accelerator

Dma simple

This example demonstrates how to insert Simple DMAs for data transfer between User program and hardware accelerator

File IO Dense Optical Flow

Linux video processing application that reads input video from a file and writes out the output video to a file. Video processing performs LK Dense Optical Flow over two Full HD frames video file. You can run it by supplying a 1080p YUV422 file route85_1920x1080.yuv as input.

File IO Stereo Block Matching

Linux video processing application that reads input video from a file and writes out the output video to a file. Video processing performs Stereo Block Matching to calculate depth in a single sample stereo video file desk_1280x720.yuv as input.

File IO Video Processing

Linux video processing application that reads input video from a file and writes out the output video to a file. Video processing includes Motion Adaptive Noise Reduction (MANR) followed by a Sobel filter for edge detection. You can run it by supplying a 1080p YUV422 file as input with limiting number of frames to a maximum of 20 frames.

Full array 2d

This is a simple example of accessing full data from 2D array

Hello vadd

This is a basic hello world kind of example which demonstrates how to achieve vector addition using hardware function

Lmem 2rw

This is a simple example of vector addition to demonstrate how to utilize both ports of Local Memory

Loop fusion

This example will demonstrate how to fuse two loops into one to improve the performance of a C/C++ hardware function.

Loop perfect

This nearest neighbor example is to demonstrate how to achieve better performance using perfect loop.

Loop pipeline

This example demonstrates how loop pipelining can be used to improve the performance of a hardware function.

Loop reorder

This is a simple example of matrix multiplication (Row x Col) to demonstrate how to achieve better pipeline II factor by loop reordering.

Row array 2D

This is a simple example of accessing each row of data from 2D array

Shift register

This example demonstrates how to shift values in each clock cycle

Sys port

This is a simple example which demonstrates sys_port usage

Systolic array

Matrix multiplication implemented as systolic array

Wide memory rw

Wide memory read write 128 bit wide

Window array 2d

This is a simple example of accessing window of data from 2D array
