Validate Embedded Platform¶
This is a simple design that verifies if the platform has basic functionalities. It also tests the possible bandwidth between Kernel and Global Memory.
KEY CONCEPTS: Bandwidth
This example contains verify test and bandwidth test to validate embedded platforms.
Using the sp
option in the zcu102_base_dfx.cfg file AXI-Master Port is connected to the IP.
sp=bandwidth_1.input:HP0
sp=bandwidth_1.output:HP0
sp=bandwidth_2.input:HP1
sp=bandwidth_2.output:HP1
sp=bandwidth_3.input:HP2
sp=bandwidth_3.output:HP2
sp=bandwidth_4.input:HP3
sp=bandwidth_4.output:HP3
Following is the real log reported while running the design on zcu102_base_dfx platform:

DESIGN FILES¶
Application code is located in the src directory. Accelerator binary files will be compiled to the xclbin directory. The xclbin directory is required by the Makefile and its contents will be filled during compilation. A listing of all the files in this example is shown below
src/bandwidth.cpp
src/host.cpp
src/verify.cpp

COMMAND LINE ARGUMENTS¶
Once the environment has been configured, the application can be executed by
./validate.exe -x <validate XCLBIN>
