Critical Issue
When you create a simulation model, the CRC compiler automatically creates a testbench directory in the project directory for you. If you follow the Running the Testbench Example steps in the CRC Compiler User Guide to create the generator and checker files, another testbench directory is created as a subdirectory of the initial testbench directory, resulting in the following directory structure:
c:\altera\projects\crc_project\testbench\testbench
when the initial directory is
c:\altera\projects\crc_project\testbench.
The testbench subdirectory (testbench\testbench) of the initial c:\altera\projects\crc_project\testbench directory may be deleted.
