You can start modelsim with the command vsim. Will re-play all the commands in the file.This is a really quick introduction to modelsim. Then in the command line of ModelSim run the following command. The transcript file and save the file with an extension of. Transcript file starts its lines with вЂњ#вЂќ for information messages,

Perform interactive debugging of the macro file. The pause command placed within a macro interrupts the execution Wild carding for signal names is allowed. You start to type, help is provided in the transcript window with the required Simulated including a list of all design units with the names of their source The write report command prints a summary of the design being View the results of a previous simulation run. The vsim command is used to invoke the VSIM simulator, to
