Virtuoso Schematic Composer User Guide

Getting Started

Using the Command Interpreter Window

The Command Interpreter Window (CIW) is the first window that appears after you start one of the executables.

The menu banner displays the Cadence® Design Framework II menus.

The message area displays messages from the software as you use the schematic composer. You can resize the CIW to see more messages in this area.

The input line is where you can type Cadence SKILL commands and functions or indicate coordinates.

The prompt line shows messages from the current command.

The mouse settings line shows the current settings for the mouse buttons (left, middle, right). The settings change as you move the mouse in and out of cellviews or start and stop commands. Press Shift to see Shift mouse bindings; press Control to see Control mouse bindings.

For details, refer to Design Framework II User Guide.
