I have implemented a small Simulink Encode and Decode system using Convolutional Encoder and Viterbi Decoder. Initially it executed perfectly for C and HDL code generation. But after some time,when try to update the diagram it throw an error above. I am not sure why this error occurs. i have included a trellis structure included from one of Mathworks example.
I have attached simulink diagram. It would be a great help to get an idea why this error occurs.
Edit 1 I think i found out why this error occurs. Whenever, i add Matlab folders and subfolders to the path in Workspace and update the model it throws above error. But when i remove folders from path and update model it compiles fine. I don't understand the reason behind this whether it relates to compilation procedure or some bug in R2016a!!?
