These ports are specific with the metal layers in different libraries. Once all the connections have been completed, the ports have to be added.This can done by using the suitable metal layers for the inter connections. Once the instances are placed they have to be joined in sync with the connections present in the schematic.Once all the instances are ready, the user can place them as he wishes in the layout editor.Once all the instances are present, some of the transistors that are to be used may not have a body contact.In the layout editor the corresponding transistors, resistors and capacitors are to be added from the same library as the corresponding instances present in the schematic.Once this is done the virtuoso layout L is opened by default. Firstly, a new cell view should be created with layout as the type and it should be present in the same cell as the schematic is present.NOTE: From now on all the references made will be related to the cadence virtuoso IC 6.15 (Only the custom digital placer is used as the circuit is DC-DC to controller.) ( The circuit can be automatically routed)Įach of the above methods will be briefed in the following sections. Using the custom digital placer for digital circuits/custom analog for the analog circuits. Manually placing the components in the and routing manually/assisted.Ģ. After the schematic of the concerned Circuit has been completed and saved, the layout of the circuit can be done in two ways.ġ.
