How to compile protected files in questa

I have a protected vhdl file.when i try to compile that protected vhdl file it shows error in protected region. Is there a different command for compiling protected files or is that same command “vcom file.vhd”. In other simulator it is working but with questa it is not working. can anyone help me with that.

In reply to vinodkumar1993:

You compile protected files in the same manner as unprotected files. If there is a syntax error within the protected region, Questa will not provide any additional information since the source code is protected.

You will need to contact the vendor that provided the protected IP for additional assistance.
