  1. OrCad Release 9.2 For Slide show 1

  2. The Objective • Open and Save New Design File • Create a Circuit Schematic • Get Place, Place Parts i.e. Resistors and Sources • Edit Part Values i.e. Resistors and Sources

  3. The Schematic

  4. OrCad Adding Parts to a schematic

  5. Take note of the “Part Search” and “Add Library” functions

  6. Or Note Power and “0” ground button

  7. Or Note Power and “0” ground button

  8. The “0” gnd pin is require for PSpice analog simulations.

  9. OrCad Connecting or Wiring Placed Parts

  10. Note - It is often highly desirable to label the nodes • of a Schematic for plan and simple clarity. PSpice will • refer to nodes by “N00004” for example. • Labeling the nodes V1, V12, etc improves efficiency. • See the “NI” button. • Click on “NI” • Type in node name i.e. V12 • Move cursor (or is it curser)to node and click to attach.

  11. OrCad Saving your design

  12. Saving Modified Design • Minimize schematic page • Locate PCB file organizer • Right click the default file name • Select “Save As” • Entering new design name

  13. Adding “Schematics” “Pages” to a Design • “Root Schematic” - to most sheet in the hierarchy. • “Page” - Where the circuit diagram is found in the schematic hierarchy. • “Schematic” - subservient circuit which can be called or descended to from the “Root Schematic”

  14. Add a new Schematic by right clicking on”\dc1.dsn” • Root Schematic - you may have only one root. • Note “\” identifier a root. • Add a new Page to any Schematic by right clicking on”Schematic” • Rename Pages or Schematic by right clicking on either.

  15. Adding “Schematics” “Pages” to a Design • It is a good idea to place all of the circuits on a given subject in the same design. • This will allow you to “make calls of these subcircuits “schematics” from the “Root Schematic”. • This eliminates duplicate reentry. More on this later.
