Release Notes

2023.2

Summary

  • Support for testing graphs on VEK280 boards
  • On VCK190, support for graphs with up to 36 input PLIOs and 36 output PLIOs
  • On VEK280, support for graphs with up to 16 input PLIOs and 16 output PLIOs
  • Performance testing mode has been enhanced to allow testing the performance of the graph with a sequence of user-provided data followed by a user-specified number of randomly generated values
  • New functional testing mode allows testing the functionality of the graph without any limit on the size of the dataset.
  • PLIO throughput for each channel is 5GB/sec (32 bits @ 1.25GHz)
  • User-defined number of replays for upscaling the size of datasets in performance testing mode on each input and output channel
  • User-defined start delay for each input and output PLIO
  • Built-in support for AIE event trace
  • SW APIs to develop a test application to run the AIE graph and transfer data to and from the AIE
  • Utility scripts to build the application and create a SD card image for board run on VCK190 and VEK280

Limitations

  • On VCK190, the performance testing mode supports up to 64kB of user-provided data per channel
  • On VEK280, the performance testing mode supports up to 128kB of user-provided data per channel
  • The functional testing mode is not supported on VEK280
  • SW emulation flow is not supported on VEK280
  • AIE graphs with GMIOs are not supported
  • The size (in bytes) of input and output datasets must be a multiple of 16

2023.1

Summary

This is the first release of the AIE Test Harness. This release supports the following:

  • AIE graphs with up to 16 input PLIOs and 16 output PLIOs
  • PLIO throughput for each channel is 5GB/sec (32 bits @ 1.25GHz)
  • Input and output datasets up to 128KB in size
  • User-defined number of replay for each input and output dataset
  • User-defined start delay for each input and output PLIO
  • Built-in support for AIE event trace
  • SW APIs to develop a test application to run the AIE graph and transfer data to and from the AIE graph
  • Utility scripts to build the test for SW emulation and create a SD card image for VCK190 board run

Limitations

  • The precompiled .xsa only supports the VCK190 board
  • AIE graphs with GMIOs are not supported
  • Datasets larger than 128KB are not supported. For longer input / output sequences, the “replay” functionality should be used
  • The size (in bytes) of input and output datasets must be a multiple of 16
