Steps for making OrCAD simulations

  1. Go to Start --> Programs -->OrCAD Release 9.1 -->Capture CIS

  2. Go to File -->New -->Project...
  3. Give a name for your project.
    Select Analog or Mixed-signal Circuit Wizard.
    Choose a folder for saving your project.
    Click on OK.

  4. For digital simulations Add (double click on) 7400.olb (conatins TTL ICs)
    For analog simulations Add (double click on) opamp.olb (conatains Op-Amps including uA741) and diode.olb (contains diodes)

  5. Now make the circuit in the schematic window. Use the following buttons:

    A sample schematic:

  6. Save your work. Click on File -->Save.
  7. Place voltage markers and run the simulations using the following buttons:

  8. View the resulting waveforms.
