Verilog $ferror is a system task that is used to report a fatal error and terminate the simulation. It is typically used in the event that an unexpected condition occurs during simulation, such as a syntax error or a problem with the design. When $ferror is called, the simulation will immediately stop and display an error message. The syntax for $ferror is:
$ferror("Error message");
The error message should be a string that describes the nature of the error.
