Logger

To print messages through the engine.print() method, noRTL requires a logger to be present in the testbech.

noRTL comes with a default implementation inside the simulation modules. It's usage and requirements are described in the logging setup guide.

You may replace it by your own implementation or customize parts of it, e.g. to add additional levels, route outputs to a file, or more. If you customize or replace the logger, please implement the Verilog functions listed below.

Logging Levels

The minimum feature set includes the 3 logging levels info, warning and error. The print handler will also forward additional levels and translate them to calls of the corresponding Verilog functions.

Print Info

function void info (string message);

Print Warning

function void warning (string message);

Print Error

function void error (string message);
