Resolution
There is a compiler bug that during emulator mode suppose to flag an warning when ever detect any vectorize kernel operation, so the compilation result should be tally with FGPA mode which is an compilation errror. A compilation fix/warning under emulator mode will be deployed in 18.0 SDK release.
