Full Custom IC Desig..

Now go ahead and click on Add Instance or simply click on this icon in the schematic
window. Select “SAED_PDK_90” for the library and select pmos4t and nmos4t for the cell
while placing their respective parts on the schematic. For pmos4t width, assign 0.5um and for
nmos4t width, assign 0.25um (Fig.7). You can also modify these properties later using the
property editor by going to Edit Properties Property Editor and selecting the component
you want to modify in schematic view.
