I have the following questions regarding orcad.
We draw the circuit diagrams and make the connections in the schematic. We create a netlist. And then we import it to the layout.
1. After importing netlist to the layout the designer should not be able to make any modifications (adding connection or component,deleting connection or component) in the layout. If yes then how?
2. But in some cases the designer may want to modify the connections and the components. In such case is it possible for the designer to modify the connections and components in the schematic and update it in the existing layout? if yes then how?
If answer for the question1 is No then,
3. Is it possible for the designer to make the modifications in the layout itslef and apply these updates to the existing schematic? if yes then how?
