Cannot apply disaggregate issue? (with Vitis 2022.1 on U250)

Hi-

With the new 2022.1 version, I got something Error during synthesizing MatrixMultiplicationKernel.

INFO: [HLS 214-131] Inlining function 'hlslib::Stream<hlslib::DataPack<float, 8>, 0ul, (hlslib::Storage)0>::Stream()' into 'MatrixMultiplicationKernel' (/home/lab/yong/SoonToBeRemoved/gemm_hls/kernel/Top.cpp:47:26)

Pre-synthesis failed.

After I added #pragma HLS aggregate variable=aSplit and do the same thing for the other variables (i.e. aPipes, bPipes), the synthesis has been also falied.

This looks related to the issue that was causing the design to fail pipelining in 2021.2. I'm afraid the accelerator is currently broken with 2021.2 or newer 😞 I will try to find time to look into this issue, but I cannot promise when I have time. In the meantime, I can only suggest using 2021.1 to compile.

This is the same issue as #25, so I will close this one.

Hello, any update on this ?
