SET Auto Pan Auto Pan controls movement past the screen boundary.
While Auto Pan is turned on, when the pointer crosses a screen boundary, the screen pans in that direction.
When you select Auto Pan, you then choose between Yes and No. Yes turns on auto panning; No turns it off.
Logic and Display Circuit
Figure 2-14. Panning changes the area of the schematic that displays.
SET Backup File Backup File controls whether or not Draft creates a backup file of your worksheet when you write or update files using the QUIT command. The backup file contains the previous version of your edited worksheet.
When you select Backup File, you then choose between Yes and No. Yes turns on the creation of backup files; No turns it off.
6. NOTE: Turning off
BackupFile can be dangerous. If your file
should accidentally be damaged
orerased, you will be
unable to recover it.
SET Drag Buses Use Drag Buses to stretch buses, rubberband-like, when you use the BLOCK Drag command. Because there are more points to locate when rubberbanding, system performance.
slows down when you use BLOCK Drag with Drag Buses turned on.
SET Error Bell
When you select Drag Buses, you then choose between Yes and No. Yes turns on rubberbanding buses; No turns it off.
Error Bell turns the error bell (your computer's speaker) on and off. When you turn this option on, error messages and errors sound the speaker.
When you select Error Bell, you then choose between Yes and No. Yes turns on the error bell; No turns it off.
SET Left Button When Left Button is on, releasing the left mouse button executes the <Enter> key for command line commands only.
Pressing the left mouse button continues to select the command highlighted in pop-up menus.
For example, suppose you select the PLACE Wire command and the "Begin Find Jump Zoom" command line displays at the top of the screen. To select Begin with the mouse when SET Left Button is turned off, you click the left button once to display the pop-up menu and once again to select Begin.
When SET Left Button is turned on, you instead press the left button and hold it down while you move the highlight to Begin, then release the left button. This selects Begin and saves one button click.
When you select Left Button, you then choose between Yes and No. If you select Yes, releasing the left button on your mouse executes <Enter>. If you select No, releasing the left button on your mouse does not execute <Enter>.
SET Macro Prompts When Macro Prompts are turned on, the commands making up your macros display on the screen when the macro runs.
Tum Macro Prompts on when debugging macros or to watch the commands being performed when you run the macro.
After selecting Maao Prompts, you choose between Yes and No. Yes turns on macro prompts; No turns them off.
~
NOTE: Setting Macro Prompts to
Noturns screen redraws off when a macro runs. This speeds up macro execution. As a result, Auto Pan
isset to
Noduring macro execution and macros using the ZOOM command won't work.
SET Orthogonal When Orthogonal is on, wires and buses are drawn orthogonally (perpendicular to each other). When turned off, wires and buses can be drawn at any angle.
Yes No
As the above figure shows, when you select Orthogonal, you then choose between Yes and No. Yes restricts wires and buses to connections at 90° angles; No places no restrictions on the angles and so you can draw wires and buses at any angle.
SEr Show Pin Numbers When Show Pin Numbers is turned on, pin numbers for library parts are shown on the screen and in worksheet hardcopies. When disabled, pin numbers are not shown on the screen or in hardcopies.
9 CLK 74LS91
Yes
--<»CLK 74LS91
No
After you select Show Pin Numbers, you then choose
between Yes and No. As the figure above shows, Yes turns on the display of pin numbers; No turns it off.
SET Title Block When Title Block is turned on, Draft puts the standard title block on the worksheet. With the option turned off, you may create a custom title block using the PLACE WirelBus and PLACE Text commands.
Yes
No
When you select Title Block, you then choose between Yes and No. Yes turns on the display of the title block; No turns it off.·
SET Worksheet Size Use Worksheet Size to select the worksheet size, A through E.
After you select Worksheet Size, choose a letter from A through E. The exact dimensions of each worksheet size are defined in the Template Table on the Configure Schematic Design Tools screen. For more information, see
Chapter 1:
Configure Schematic Tools.
SET X,Y Display When X,Y Display is turned on, the upper right part of the prompt line shows the pointer coordinates. The work-sheet origin (0,0) is the upper left corner. Coordinates do not appear on the screen until the pointer is moved.
2.20 .30
Yes No
When you select X, Y Display, you then choose between Yes and No. Yes displays pointer coordinates; No doesn't.
• CAUTION: When grid coordinates are not displayed, it is
easy to make small errors when placing parts, wires, and
buses. These errors may cause problems when using the
Check Electrical Rules reporter and Create Netlist
processor. This is because wires and buses may look as if
they are connected when they are not. Check Electrical
Rules and Create Netlist interprets these incomplete
connections as opens. Do not place parts, wires, or buses in
the worksheet with
X,Y Display disabled or with Stay on
Grid turned off (described on the next page).
SET Grid Parameters
Grid References
Stay on Grid
Visible Grid Dots
Select Grid Parameters. Draft displays the menu shown at right.
Use Grid Parameters to display grid references, keep the pointer on grid, and display grid dots.
Set Grid Parameters Grid References NO Stay on Grid YES Visible Grid Dots NO
When Grid References are turned on, Draft displays an alphanumeric border on two of the four worksheet sides.
The top border shows grid reference numbers, and the left border shows reference letters. The borders are scaled to the size of the worksheet. Grid references can be used as
destination for the JUMP command.
When Stay on Grid is turned on, the pointer location is confined to the predefined grid. When disabled, the pointer may be moved off-grid to any position on the worksheet at a resolution ten times that of the grid.
After you select Stay on Grid, you select either Yes or No.
Yes restricts the pointer to the grid; No does not.
CAUTION: Placing parts, wires, and buses with Stay on Grid turned off may cause problems, because wires and buses may look as if they are connected when they are not.
Unconnected wires and buses are reported as errors by the Check Electrical Rules reporter and Create Netlist processor. To avoid trouble, do not place parts, wires, or buses in the worksheet with Stay on Grid turned off.
When Visible Grid Dots are turned on, grid dots display on the worksheet. When grid dots are visible and SET Stay on Grid is turned on, it is easier to place parts at specific points on the worksheet.
The distance between grid dots depends on the current zoom scale. The table at right lists the grid dot spacing at different zoom scales.
After you select Visible
Zoom
SET Repeat Parameters Repeat Parameten are used to determine how the REPEAT command works.
Select Repeat Parameten.
Draft displays the menu shown above.
Set Repeat Parameters
X Repeat Step 0
Y Repeat Step + 1 Label Repeat Delta + 1 Auto Increment Place NO
X
Repeat Step
X Repeat Step determines the number of unit steps in the X direction the object being repeated is offset from theoriginal object. The X direction goes horizontally across the worksheet, with positive to' the right and negative to the left of the current pointer position. A unit step in the X direction is defined as ~o of an X unit when SET Stay on Grid is turned on and 1Aoo of an X unit when SET Stay on Grid is turned off. You can view the change in X units as the pointer moves on the display by turning on the SET X,Y Display option.
When you select X Repeat Step, the prompt IIX Repeat Step?" displays. Enter any integer.
Y
Repeat Step
Y Repeat Step determines the number of unit steps in the Y direction the repeated object is offset from the original object. The Y direction goes vertically on the worksheet, with positive above and negative below the current pointer position. A unit step in the Y direction is defined as Ito of a Y unit when SET Stay on Grid is turned on and ~oo of a Y unit when SET Stay on Grid is turned off. You can view the change in Y units as the pointer moves on the display by turning on the SET X, Y Display option.When you select Y Repeat Step, the prompt lIy Repeat Step?" displays. Enter any integer.
