MENTOR GRAPHICS DESIGN MANAGER TUTORIAL

The entry point into the Mentor Graphics suite of tools is through Design Manager. Design Manager is a graphical shell that allows you to launch applications and manage your designs. All operations that can affect your designs must be done through Design Manager. For example, Design Manager allows you to delete, rename and copy designs. While the UNIX commands rm, ren and cp allow the same operations to be performed, they do not know how to update the Mentor Graphics database. USE ONLY DESIGN MANAGER FOR SUCH OPERATIONS.

 

To invoke Design Manager, follow these steps:

 

1.      Log onto a UNIX machine.  Get a terminal window (right click, Tools, Terminal), create a sub-directory in your home directory where you will store your Mentorgraphics files.  Move to this directory by typing “cd your_new_directory_name”

2.      Type "dmgr &" at the prompt. This command starts up Design Manager.  (Do not type the " " only what is inside the  " ")

3.      A window similar to Figure 1 will appear.

The left half of the window shows the available tools. The right half shows your directories.  The arrows at the bottom of the file window allow you to move through the directory structure, double left-clicking will also open a folder.  More on these functions later.

 

The main Design Manager window or the inside windows may be moved, resized, minimized or closed in the same way other windows are manipulated. You must click on the window to be manipulated, first, however.

 

Before going any further, let's take a look at some Mentor Graphics basics. In Design Manager, and most other tools, the left mouse button is used to click on (or select) items. The right mouse button is used to bring out pop-up menus. The pop-up menus are context sensitive. That is to say that, depending on where your mouse pointer is when you right-click, a different menu may appear. Try this now by first selecting the left tools window and then using the right mouse button to bring up the pop-up menu. You must click in the window, not on the title bar or window border. Notice how the menu's title is ``TOOL OPERATIONS.''  Now do the same for the right window. Here, the pop-up menu is different and is context sensitive.

 


 


 

 

To begin our tour of Design Manager, start by maximizing the window by using the maximize button in the upper right hand corner of the window. The window should now fill the entire screen. You will notice that the inner windows got larger but their contents don't fill the new areas. To clean up your windows, use the right mouse button to bring out the pop-up menu in the Tools window and select "UPDATE WINDOW". Now, the whole area of the window will be better used. You can now see many of the tools that Mentor provides for your use. These will be described in detail in their respective tutorials, but we will use one, the Editor, for this exercise.

 

Let's start by invoking Editor from the Tools menu. Simply double click on the editor icon to bring up an editor window.  Follow the instructions below to create a file, save it and view it in the navigator window.


 

  1. Notice how the border of the editor window is a cyan color. This shows you that the editor window is currently active. If it is not active, simply click anywhere in the editor window to make it active.
  2. To enter text, simply start typing. Type your name or anything else you like.
  3. When you are finished typing save this file by using the menu, Select "File>Save" to save it.

 


 

  1. Since this is a new document, you will be prompted for a filename. Use the name tutorial. After you have entered the name, you should see that the top line of your editor window displays the filename including the path.

 

 

 

  1. Close the file. To do this, simply close the editor window by using the upper left button of the window. To do this, select it so the pull-down window appears and drag down to (or select) Quit.
  2. Now look in the navigator window. Do you see the file you just created? The reason you do not is that the Design Manager does not know you created it. You need to update the navigator window. To do this, just as before, select "Update Window" from the pop-up menu in the navigator window. Now you should see the file object called tutorial.
  3. You can rename the file by selecting the object, using the left mouse button, and then using the pop-up menu item "Edit > Change > Name".

 


8.      When the dialog box appears, enter a new name for the object. Just hit return or the "OK" button to accept the name.  Notice how the name was changed in the navigator window. You don't have to use the update window command when Design Manager performs a task since Design Manager knows about the task performed. The editor, however, was not a Design Manager command, but an external program.

 

Now, let's look at how the navigator window works. The bottom of the navigator window has five buttons with arrows. These are described below:

 

·        The down arrow is used to descend down a directory level. You first select a folder object, then this arrow becomes ungrayed and you can descend into the object's path.

·        The up arrow is used to move up a level from the current directory.

·        The right arrow is used to show information about a file.

·        The left arrow moves you back a level from the actions the right arrow initiates.

·        The four arrows button is the go to button. By selecting this button, you may enter a path where you would like to go to.

 

Let's use the navigator's buttons to move around the system.

 

1.      First, select your file if it is not already selected. Note how the right arrow becomes ungrayed.

2.      Select the right arrow to view information about the file. The window is empty. This is because a text file has no links in the Mentor database. When you create schematics, however, they will have objects that do have links to other objects, such as library components. 

3.      Move back by using the left arrow.

4.      Move up to your home directory by using the up arrow. Notice how the contents of the navigator window now show  your home directory. The folders are subdirectories, and the plain rectangles are files that Mentor does not recognize.

5.      Move back into the Mentor directory by selecting the Mentor folder icon and using the down arrow, or by double clicking on the Mentor folder.

 

You now know how to navigate using Design Manager. You can also view parts of your designs using the navigator, and you can do maintenance on your designs, such as copying them, deleting them, and renaming them by using the pop-up menus as discussed above. Select the appropriate operation and you will be prompted for any additional information.
