Creating Schematic Symbol in Orcad

byMichael L. P. Tan

Step 01 - Schematic we wanna symbolize

Step 02 - Copy Schematic to Library

Step 03 - Go to the schematic within the library file and remove power supply

Step 04 - Power supply removed. This will be used as our symbol. Current comes out from the positive node.

Step 05 - Create new part named ptype_cnt

Step 06 - Go to option then select package properties

Step 07 - How to fill the Implementation part

Step 08 - Name the symbol

Step 09 - Create new project to test the symbol

Step 10 - New project - test circuit.dsn

Step 11 - Add the library CARBONNANOTUBE

Step 12 - Edit the properties of the part

Step 13 - Change primitive to NO

Step 14 - To make the wiring easier, to to option and click on wire drag

Step 15 - Input and output for the symbol

Step 16 - I-V is given but we wanted positive current

Step 17 - Add library and edit the schematic

Step 18 - Edit the circuit

Step 19 - Update Cache everytime you changes the library part schematic
