All the product blocks used the Shift-Add architecture. Switching back to Linear eliminates the error. Still not clear what exactly is happening.
Evaluation of elaborate function error in HDL coder

I get the following error when trying to generate HDL from a simulink model with HDL Coder:
Error: Evaluation of elaborate function on class hdldefaults.NonRestoreDivide failed with the error message: MATLAB:UndefinedFunction: Undefined function 'Signed' for input arguments of type 'hdlcoder.tp_single'.
The model runs fine in simulink. I cannot find anything helpful about any terms in this message and no link is given to any specific point in the model. I first got the error when I added a number of single precision floating point multilpy and divide blocks into the design. I reworked it to use all multiplies and a single reciprocal block but still get the same problem. I am using prelease matlab 2019b. What is the root of the problem and is there some way to track it down to a specific point in the design?

This seems like a general guidance and unrelated to the internal HDLCoder error. Please see my answer to the question.

This is an unexpected error from HDLCoder. Will it be possible to share the model? We can evaluate and provide the workaround.
