This error indicates that the file referenced in the $fscanf command could not be found. This message is preceded by a file not found message such as the following:

WARNING: at 100 ns: file ./sim/data.txt could not be opened
ERROR: File descriptor (0) passed to $fscanf is not valid

This error has been seen with several root causes such as the following:

1. The file path delimiters are incorrect for the operating system: "\" instead of "/" in UNIX.
2. The file path is incorrect
3. The file does not exist

To resolve this error, ensure the file exists, and the path is correct, using the correct path delimiters for the operating system.
