DVT SystemVerilog IDE User Guide
Rev. 21.1.31, 27 July 2021
In files that contain encrypted code, DVT may signal errors for mismatched language tokens, e.g. "Unexpected token 'endmodule'". The cause of this type of errors is most of the times the asymmetric encryption done to the code, e.g. an endmodule or an endif inside the encrypted code with the corresponding module or ifdef outside it, in plain text.
Because DVT ignores encrypted code, some of the types may end up been compiled in the wrong scope altogether. To restore full or partial functionality, the asymmetric encrypted code must be fixed e.g. adding the missing endmodule.
When the encrypted files are read-only, you will have to substitute the original broken files with the fixed ones.
Having done the above, DVT will use the substitute files and offer valuable functionality, like hyperlinks, type hierarchy, references in the now correctly compiled code.
Note The + dvt_file_substitute directive accepts only absolute paths as arguments. Environment variable can be used to define the absolute paths. Regular expressions are not supported.
