Edit Menu


Undo

The Undo command (Edit -> Undo) is useful to not take into account the last editing command. It is possible to undo the commands Cut, Paste, Copy, Move, Stretch and Edit.

Cut

Click on the Cut icon. Move the cursor to the design window, and delimit the active area with the mouse. Consequently, all the graphics included in this area are erased. Click on Undo to fix those elements back into the design.

Copy

Click on the Copy icon. Move the cursor to the design window, and delimit the active area with the mouse. Consequently, all the graphics included in this area are copied. The external shape of the copied elements appears. Fix those copied elements at the desired location by a click on the mouse.

Click on Undo to cancel the copy command.

Paste

All the graphics previously deleted or copies may be fixed again on the layout at the desired location by a click on the mouse.

Move

To move one graphical element, click on the "Move" icon or "Edit -> Move". Then using the mouse, draw an area that includes the elements. Then, drag the mouse to the new location and release the mouse. As a result, the elements are moved the new place.

Flip Horizontal and Vertical

To apply a flip to one part of the design, click on Edit -> Flip. Then, delimit the area inside which the elements will be changed.

Rotate

To apply a rotation to one part of the design, click on Edit -> Rotate. Select one of the proposed action:

Then, delimit the area inside which the elements will be rotated.

Line

The " Line " icon is the default icon. It creates an interconnection between two points in the schematic diagram. If the " Line " icon is not selected, click on it. Then, move the cursor to the display window and fix the start point of the interconnect with a press of the mouse. Keep pressed and drag the mouse to the interconnect end. Release the mouse and see how the line is created.

Connect

Use the "Connect " icon to create the electrical contact between crossing interconnects.

Text

Text is added for information only. It has no impact on simulation. Text is usefull to add comments on the schematic diagram, add more information or specific I/Os or nodes.

Note that text starting with "." is usually considered as a simulation command. For example: ".TRAN 0.1NS 100NS" is a text that is also considered as a SPICE control to configure the transient simulation.

Keyword Used for Example
.TRAN transient simulation .TRAN 0.1NS 100NS
.DC dc simulation .DC Vin 0 5 0.1
.AC AC simulation .AC DEC 10 1MEG 1G
Kxxx Inductance coupling K2 Ltem2 Lvdd 0.002
.OPT WinSpice option .OPT RELTOL=1e-6
