Agilex 5: Cascading DSPs in tensor-mode doesn't work

Hi, In my design for Agilex 5 I have two DSPs, configured in tensor fixed-point mode with side feed control, cascaded together. I expect the summation of the dot products in the second (last-in-chai...

Hi,

 

As I understand, you have questions regarding the Agilex DSP behavior, where the observed output does not match your expectations. To ensure we are aligned and to help me better understand the issue, could you please assist with the following:

 

Simulation case
Please share a simple test design and simulation setup, with steps to replicate the simulation, along with a brief description or illustration of the expected behavior.

 

Hardware reproduction
Please also share a minimal hardware test design that can reproduce the issue, together with steps to replicate and SignalTap captures highlighting the unexpected behavior.

 

This information will help me better understand the DSP IP configuration, test setup, and observed behavior, and will greatly facilitate further debugging.

 

Please feel free to let me know if you have any questions or need clarification. Thank you.
