1. Open up your schematic

2. Launch ADE explorer (create new view)

3. Create a Design Variable (PCCVAL = 0.9)
   (you will sweep this 0.8, 0.9. 1.0)

4. Setup Stimuli
     PCC = PCCVAL
     PSS = 0.0

5. Setup-->Job_Setup-->Local

6. Outputs-->Add-->Signal np, nn
             Add-->Expression value((VDC("/np") - VDC("/nn")) 0.9)

7. Analysis dc  (sweep design variable PCCVAL = 0.8, 0.9, 1.0)
