    Study Notes

    Display Tasks

    • Display system tasks are used to display informational and debug messages to track the simulation flow from log files.
    • There are three categories of display tasks: Display and Write tasks, Verilog strobe, and Continuous monitoring tasks.

    Display and Write Tasks

    • $display and $write tasks are similar to the print function in ANSI C language.
    • The main difference between $display and $write is that $display adds a new line character at the end of the output, while $write does not.
    • Syntax: $display() and $write().
    • Both tasks display arguments in the order they appear in the argument list.
    • If no argument is specified, it is declared a null argument, and a single space character is printed when the task is invoked.

    Verilog Strobes

    • $strobe prints the final values of variables at the end of the current delta time-step.
    • Format is similar to $display.
    • A newline is automatically added to the text.
    • Example: $strobe is used to print the values of variables at specific times in the simulation.

    Verilog Continuous Monitors

    • $monitor helps to automatically print out variable or expression values whenever the variable or expression in its argument list changes.
    • Achieves a similar effect of calling $display after every time any of its arguments get updated.
    • A newline is automatically added to the text.
    • Example: $monitor is used to continuously monitor and print the values of variables throughout the simulation.
