'Failed aType != nullptr' error during HDL code generation

Hello,

I am attempting to build a set of Simulink models for HDL code generation, and am having trouble in the 'Generate RTL and IP Core' step of the HDL Workflow Advisor. The HDL code generator fails with the following error:

 "Failed aType != nullptr".

I have been unable to find any solutions to this online, and there is very little information given about the error. What can I do to take steps towards solving this problem?

Thank you,

Jason Meyer
