When I try to use the SI core engine block, I get the following warning message.
"Warning: Could not evaluate MaskDisplay commands of block 'untitled/SI Core Engine': Undefined function 'autoicon' for input arguments of type 'char'.
What's the reason?

Hi Kumara,
Can you try the following troubleshooting steps:
1. Run the following commands in your MATLAB command line
>> which -all autoicon
>> license('checkout', 'Powertrain_Blockset')
2. Please check if your MATLAB path contains the following links:
Here, matlabroot is the path to the installation folder, for example
"C:\Program Files\MATLAB\R2016b"
You can observe your MATLAB path with the command
>> matlabpath
3. You could try one of the following commands to see if it solves the issue:
>> restoredefaultpath
>> rehash toolboxcache
