Schematics tutorial Spring 2004 Creating Schematic (1) By this point you are in Cadence and have created a library Inverter and a layout cellview Inv1. (2) Now create a schematic cell view using: File>New>Cell View. This will open up a new window. Choose the Inverter library and fill in the cell name with Inv1: Then, click ok. This will open up a blank schematic window. (3) Instantiate the transistor models from the library (a) Press “i” while the schematic window is active. (You can also use the pull down menu from the schematic window). This will bring up 2 windows as shown below à (b) Choose the correct transistor model and fill the desired size. Then click Hide and place the transistor in the schematic window. (c) After you have placed all device symbols down. You can use wires (hotkey w) to connect all the devices together to create an inverter as shown below. Use Add Pin to put down input, output and supply pins that match the pins you created in the layout view. ààà Cross Probing with Virtuoso Layout Editor and Schematic Composer Once you have drawn both the layout and schematics, you can use the cross-probing function. This allows you to select a piece of layout and highlight the corresponding object in the schematic, or vice versa. You can initiate cross probing from either the Layout Editor or Schematic Composer. Tools Setup (1) Setup Layout XL. This is a powerful tool that allows you to ...
