Getting started

Start Cadence virtuoso environment by executing 'virtuoso &' from the directory where cds.lib file is located. Virtuoso starts with screen shown below:-

Starting screen of virtuoso environment.

Select 'Library manager' from 'Tools' in virtuoso environment --> Library manager starts with screen shown below:-

Starting screen of library manager


In the log window, choose "File > New > Library".

In the "New Library" dialog box, you must give the library a name (for example TORLIB, as I did). You must also specify a technology file. Here you choose "Attach to an existing technology library". Then click the OK button. When asked for technology, choose "tsmc13rf". If you are using IHP instead, choose "SG13_dev".

After successfully creating the new library, it is time to create your first design. In the log window, choose "File > New > Cellview". In the "Create New File" dialog box, you must give the design a name. You must also specify which library the design belongs to, and here you specify the library that you have just created. Choose to open the cell with "Schematics XL" and add a check-mark to always use this application if it is not checked.

Now click OK, and the Virtuoso Schematic Editor should pop up. We will now draw a simple inverter design, as shown in the picture:
