You can follow one of these workarounds to fix this issue.
  1. Please set the size on all ports for which the error is reported (don't forget to subtract one from the reported numbers!).
  2. Sometimes, Shortening the model file name fixed this issue in at least one case. (The name had been over 68 characters.) Error might possibly be something to do with the filename being too long, so MATLAB was reading the first so many characters and getting multiple files that differ in name only after the cutoff confused.

Hiii Mr.shadaab ,Thanks for your reply. I tried the second fix, but it is not resolved the issue. But I don't know how to change the port size. Need your suggestions.
