CNN Synthesis fail : ERROR: [XFORM 203-504] Stop unrolling loop 'Product1' (firmware/nnet_utils/nnet_dense_latency.h:37) in function 'nnet::dense_latency<ap_fixed<2, 1, (ap_q_mode)5, (ap_o_mode)3, 0>, ap_fixed<2, 1, (ap_q_mode)5, (ap_o_mode)3, 0>, config6>' because it may cause large runtime and excessive memory usage due to increase in code size. Please avoid unrolling the loop or form sub-functions for code in the loop body. ERROR: [HLS 200-70] Pre-synthesis failed.

> The reuse factor is capped at the number of parameters for each layer, correct? I have valid reuse factors ranging from 1, 2, ..., to 18432 for a conv2D...

Unfortunately, there is no more documentation than the tutorials, website and papers. Please have a look here: https://github.com/fastmachinelearning/hls4ml/blob/main/hls4ml/templates/vivado/nnet_utils/nnet_dense_latency.h. The code is short and the most important part of it is...

Make im2col default option for quartus

> I'm fine with this type of change. But last I remember, im2col often didn't even synthesize so we added some heuristic to at least try winograd if possible. @bo3z...

Ask about sw - rdma_service

@maximilianheer can you help with this?

Ask about sw - rdma_service

Writeback is a memory mapped region. It's a set of control registers for each vFPGA that gets incremented every time a data transfer is completed (there are dedicated registers for...

Coyote v2 RDMA fails under certain benchmark

The 8K bug has been fixed in #86. The issues with reads where due to Coyote background processed being terminated before finishing the test. @maximilianheer has debugged this and created...

Hello, after converting GRU network to IP core using hls4ml, the output of IP core is not always 0. Here is my conversion code.

Can you please add a few more details? Output from which is not zero: CSim (csim=True in hls4ml.build(...)) or the hls_prediction? Does the line np.testing.assert_allclose fail or something later?

Hello, after converting GRU network to IP core using hls4ml, the output of IP core is not always 0. Here is my conversion code.

Unfortunately, we don't provide examples of how to integrate IPs into larger application, as this is application-specific and can be done in many ways: 1. You could stream the data...

Hello, after converting GRU network to IP core using hls4ml, the output of IP core is not always 0. Here is my conversion code.

Once you have the IP, it doesn't matter what the underlying architecture is (GRU or CNN or FC etc.). At that point it's a matter of properly connecting all the...
