Hi , I tried to generate hdl code for 20*20 matrix A multiplied with 20 *1 matrix B. But HDL code generation failed saying matrix inputs not acceptable. Please help how to proceed. Thank you!

hi satish, can you share more details?are both A and B inputs to the DUT or only one of them, what are the types, are you looking for fully parallel implementation or are you looking for any serialization or area reduction options in terms of DSP reduction for the partial products? please share a sample model with your usecase for additional guidance.

Yes kiran, both A and B are inputs. I need a multipler design.

Yes parallel implementation would be better. I need to generate VHDL code for the multiplier. I want to implement the design in FPGA.

Attaching few flavors of matrix multiplication compatible with HDL Coder.
  1. matmul_external_memory_20b.slx
  2. matmul_mlfb_fixpt_20b.slx
  3. matmul_with_const_20b.slx
  4. matmul_single_streaming_20b.slx
  5. matmul_single_20b.slx

You can do this to open the models. The models do not use any new 20b features.
>> set_param(0, 'ErrorIfLoadNewModel', 'off')
