in Spring 1999 for CS755.
To invoke Design Manager , follow these steps:
Change directory to mgc.
Type dmgr at the shell prompt. This command starts up Design Manager .
The left half of the window shows the available tools. The right half shows your
Mentor directory(navigator window) which is where you should store all of your Mentor designs. Your
directory will probably be empty as you have not, as yet, created any designs.
The main Design Manager window(session window) or the inside windows may be moved, resized, minimized or closed
in the same way other windows are manipulated. You must first click on the window to be
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.
The Design Manager Users Reference of the Mentor Graphics INFORM
manual database has more information about the different parts of the Design Manager window and how to
read and use them. Contact your TA for more information about how to access this database.
To begin our tour of Design Manager , start by using the maximize button in the upper right corner of the window
frame to make the window as large as possible. 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.
- 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.
- To enter text, simply start typing. Type your name or anything else you like.
- When you are finished typing, save this file by using the menu. Select File -> Save to save it.
- 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.
- 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.
- 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
- 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.
- When the dialog box appears, enter a new name for the object. Just hit return
or click on 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
- 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
- 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.
- First, select your file if it is not already selected. Note how the
right arrow becomes ungrayed.
- 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.
- Move back by using the left arrow.
- 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.
- 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.
- Use the arrows button to go to the temporary directory. Click on the
arrows button (the ``go to'' button). A dialog box appears.
- This dialog box has a list of the last five directories that you have been to
during this session. You can either choose one of these or enter another path. You should
type in /tmp and hit carriage return.
- Now, you have moved to the temporary directory. There may be files here, but
you can ignore them. Move back to your Mentor directory by using the go to button and
highlighting the Mentor directory ($HOME/mgc) in the path list and clicking on OK.
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 database files, 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 information needed to complete the desired operation.
