May 25, 2021 · In this tutorial I’ll be explaining how to use .do files in conjunction with ModelSim and VHDL to simplify the simulation process and run rigorous tests of your system.

DO files are an automation tool in ModelSim. This tool allows ModelSim to automatically assign values to inputs in a simulation, run or restart the simulation, or even automatically verify circuits. This document explains how to use DO files to automatically assign inputs and run the simulation in ModelSim. How DO files Work DO files are ...

Jan 15, 2015 · I am working in VHDL (with Microsemi's Design Suite, Libero) and I use ModelSim to simulate my work. To that extent, I use a classic VDHL TestBench and, to save time, a .do Macro File. This .do Macro file contains very basic commands such …

Feb 16, 2014 · do file. The do file is a script that executes multiple commands at once. This script can be as simple as a series of ModelSim commands with related parameters, or a Tcl program with variables, execution conditions, etc. The Do file can be executed in the GUI or after the system command prompt. There are many ways to create a do file.

First, how do we create DO files? There are quite a few methods. One is to open Modelsim, execute the File/New/Source/Do command, enter the Do file editing mode, enter the code of the simulation batch file in the edit window, and save the file with the .do extension.

Mar 26, 2018 · .do files are tcl scripts. Have you looked at a tcl language reference? There ought to be one in the Modelsim documentation. –

Mar 27, 2014 · In a .do file you can generate the clock signal, the reset signal, input signal needed to run the simulation. Another (more flexible but a little complicated) way is to create a tesbench in vhdl.

That file can be edited and used as INPUT to the simulator so you do not have to keep restoring your state. These command files are called “do” files. The transcript file starts its lines with “#” for information messages, these are comments for a do file.

This is how to create a Do-file. Paste text commands above in the file. Then save it among the other files (in MAXwork) with extension .do. You run a Do-file with these commands (in Transcript): restart -f do lock.do. Find in the Wave window. It can be difficult to find what you are looking for in the Wave window. Therefore, there is a

We don't know that Modelsim perfectly supports the TCL scripting language and batch command do files. Simply put, after you modify the code to when you recompile, pull out the signals you need to view, and now only need one action to complete.
