Thank you for quick reply, but since i am new to orcad I had put the wrong question. So once again I have put the question with the correction, Please reply....
I am designing a PCB using orcad. I put all the components in the schematic and make the connections and I create a netlist and hence the layout.
The questions are,
1) If I change any connection or component in the layout then it should show the error indicating that it is not in schematic.
2) Some times i may forget some connections in the schematic. In such case if I add any new connection in the layout then it should be applied to the schematic.
