Features That Work With Ultiboard 7
===================================

- Cross Probing. The component selected in Multisim 7 will be highlighted
  in Ultiboard 7.

- Backward and forward annotation is supported with Ultiboard 2001. The
  complete set of annotation options are supported in Ultiboard 7.

Updates
=======

The following provides further clarification on features and functions beyond 
that described in the manual:

General
=======

By default the Spreadsheet view and the Project Browser are set to hidden. To
view these choose the View/Toolbars/Spreadsheet or View/Toolbars/Project Bar, 
respectively. You can also toggle these On and Off from the Multisim toolbar.

Schematic Capture
=================

1.  To add an arrowhead to a graphical line right-click on the line and choose 
    Arrow from the context menu.

2.  When you add a "multi-page" or flat-page to a design the new pages are 
    are saved with the same base name as the root page followed by a "#" 
    and then the page name. For example, a page called "supply" that is added 
    to "main.ms7" will be called "main#supply.ms7" and will be stored in the 
    same folder as "main.ms7"

3.  When opening a Multisim 2001 design in Multisim 7 a new file is created 
    with the same base name as the original and the new extension ".MS7".
    If a file with the same Multisim 7 name is already open you may 
    experience a problem when using copy/paste. To avoid this, close the 
    Multisim 7 file before opening the Multisim 2001 circuit.

4.  Use the arrow keys to move a selected label or Ref ID by 1 pixel or 
    PgUp/PgDn to move by 1 grid point.

5.  Use the arrow keys to move a selected part by 1 grid point or 
    PgUp/PgDn to move by 9 grid points.

6.  When copying a circuit that contains subcircuits to a new circuit 
    it is necessary to use Paste Special/Exact Copy for each of the 
    individual subcircuits.

7.  Copy and paste of a bus. The destination will show the full bus name, 
    e.g. data.D0, etc. To show only the wire name, i.e. .D0, choose 
    Options/Preferences and deselect "Show Node Names" on the Circuit tab.
    Next, select Options/Preferences and select "Show Node Names" on the 
    Circuit tab.

8.  Bus node names are locked in place even when a chip connected to the bus
    is moved. To automatically reposition the node names use    
    Options/Preferences and deselect "Show Node Names" on the Circuit tab.
    Next, select Options/Preferences and select "Show Node Names" on the 
    Circuit tab.

9.  To print instruments placed in subcircuits or hierarchical blocks go to
    the page containing the instrument and choose File/Print Instruments.
    Instruments on subcircuits or hierarchical blocks are not printed 
    when File/Print is used from a higher-level page.

10. Opening a Multisim 2001 circuit as a hierarchical block will cause
    an "Invalid or old file format" message. To fix, open the Multisim 2001
    file and save to Multisim 7 format before attaching as a hierarchical
    block.

11. Nets connected to subcircuit pins take the same name as the pin. If you
    rename a pin within a subcircuit the pin will be disconnected from
    the higher-level connection as the net names will be different.

12. Only one project file can be opened at a time. As well, only one OrCAD
    project can be opened at a time.

13. If you rename a circuit file that is part of a hierarchical design 
    Multisim 7 will no longer be able to locate the page and will report 
    the message "Failed to Open Document".

Simulation/Analyses
===================

1.  Sample files used in the analyses chapter (Chapter 9) are available in the 
    Samples folder.

2.  Ammeters and voltmeters do not work in subcircuits. That is, results
    are not generated when the design is simulated from a higher-level page.

3.  Pole-zero analysis cannot be used with digital components or the 
    Control Function Blocks in the Source bin.

4.  Post processor expressions are saved with Multisim and can be used with 
    different designs as long as the variable names are the same.

5.  When simulating digital components it's advisable to set the 
    Simulate/Digital Simulation Settings to "Ideal" in order to improve 
    simulation performance. Use the "Real" setting for greater accuracy.

6.  The frequency counter should not be used to measure frequencies below
    20Hz and operates with best accuracy above 50Hz.

7.  Setting the four-channel oscilloscope. Changing the settings on one 
    channel will affect the display of the traces of the other channels.

8.  To set parameters on the sources (e.g. AC_VOLTAGE) double-click on
    device and select the Value tab. Left-click and roll the mouse to view 
    all the parameters available. Choose "OK" when finished.

9.  When using the I-V Analyzer be sure to manually stop the simulation 
    after the plot has been generated. The simulation will continue
    indefinitely otherwise.
