ORCAD CAPTURE (PSPICE):-

Procedure:

Steps to create modeling by using ORCAD CAPTURE/PSPICE:1. Click on File New Project.2. On Resulting window give the name of project using mostly starting

with letters

(a-z) followed by numbers like for EXAMPLE gopi12 is the name of

the project.3. Create a New Project using Analog or Mixed Signal Circuit Wizard.4. Give the Location of Project by Default it goes into C: DRIVE click

on new folder save the file name as PSPICE.5.No Need to add any PSPICE part libraries to project.6. Click on Finish.7. You will Observe ORCAD CAPTURE SCHEMATIC Page which is

used for simulating the circuits.8. Place the components in SCHEMATIC using keyboard shortcut as

P button, W button stands for wiring components and finally place theground which is named as 0 from PSPICE parts list. Ground is

compulsory for simulating the circuit using PSPICE.

Simulating the SCHEMATIC:-

AFTER Completing the Schematic circuits like this click on NewSimulation Profile give any name using letters for EXAMPLE(dedefffrf) then Click ENTER. It will ask to give Simulation

parameters. You have to give start time as 0. And stop time as dependson Schematic circuit parameters, So give stop time values like 5sec.,

0.1sec, 0.1m, 3m etc. mostly in lower values.
