A method includes storing first macros that define colors of text generated during a simulation of a design under test (DUT) of an integrated circuit (IC). The method includes mapping second macros to the first macros based on a plurality of colors, where each of the plurality of colors is associated with one of a plurality of report messages generated by executing the second macros. The method includes conducting the simulation of the DUT, and displaying, based on the conducted simulation, the plurality of report messages in a format where each of the plurality of report messages is displayed in a color associated with the report message.
