The document provides steps to create a schematic design in OrCAD Capture CIS including: 1. Creating a new project and specifying the project type as schematic. 2. Adding parts by selecting them from libraries and placing them on the schematic page. 3. Connecting parts by drawing wires between valid connection points. 4. Adding input and output ports by selecting them from libraries and customizing properties. 5. Creating tools like cross reference reports, bills of materials, and simulation profiles to prepare the design for simulation and synthesis.

1. Creating a schematic design in OrCAD Capture CIS:
Design Steps:
I.
Creating a New project:
1. Launch Capture.
2. From the File menu, choose New – Project.
3. In the New Project dialog box, specify the project name
4. To specify the project type, select SCHEMATIC.
5. Specify the location where you want the project files to be created and click OK.
7. Click OK to create the project
II.
Adding parts
1. Choose Place – Part.
2. In the Place Part dialog box, first select the library from which the part is to be added and
then instantiate the part on the schematic page.
3. To add 7400.OLB to the project, click the Add Library button (*) , select pspice and then
select 7400
3. Browse to
<install_dir>/tools/capture/library/pspice/7400.olb.
Select 7400.OLBand click Open. Alternatively, you can double-click 7400.OLB. The 7400
library appears in the Libraries list box.
4. Browse to
<install_dir>/tools/capture/library/pspice/eval.olb.
Select EVAL.OLBand click Open.
5. Select 7400in the Libraries list.
6. Select 7408(AND gate) from Part List.
7. Click the Place Partbutton ( ) or click Enter.The part symbol is attached to the pointer.

2. 8. Click on the schematic page to place the part.
III.
Connecting parts
1. From the Place menu, choose Wire. The pointer changes to a crosshair. Clicking on any valid
connection point ends a wire.
2. Similarly, add wires to the design until all parts are connected
3. To stop wiring, right-click and select End Wire. The pointer changes to the default arrow.
IV.
Adding input and output ports
1. To select the input, select SOURCE libraries, and then select DigClock. You need to
customize the OFFTIME, ONTIME, DELAY, STARTVAL, OPPVAL of the DigClock to use as
input.
2. To select the output port, select Place Net Alias (N) from place part. You can customize the
output name, and text color, rotation.
V.
Simulation and Synthesis
A) Creating a cross reference report
A cross reference report contains information, such as part name, part reference, and the
library from which the part was selected.
1. Choose Tools– Cross Reference.
2. In the Cross Reference Parts dialog box, ensure that the Cross reference entire design
option is selected.
3. In the Mode section, select the Use Occurrences option.
4. Specify the report that you want to be generated.
5. In case you want the report to be displayed automatically, check View Output.
6. Click OK to generate the report.
B) Generating a bill of materials
A bill of materials is a composite list of all the elements you need for your PCB design. Using
Capture, you can generate a BOM report for electrical and as well as non-electrical parts, such
as screws. A standard BOM report includes the item, quantity, part reference, and part value.
1. Choose Tools- Bill of Materials

3. 2. To generate a BOM report for the complete design, ensure that the Process entire design
option button is selected.
3. The preferred mode is the occurrence mode. Therefore, select the Use Occurrences option
button.
4. Click OK
C) Creating a simulation profile
1. From the PSpice menu in Capture, choose New Simulation Profile.
2. In the New Simulation dialog box, specify the name of the new simulation profile as TRAN.
3. In the Inherit From text box, ensure that none is selected and click Create. The Simulation
Setting dialog box appears with the Analysis tab selected.
4. In the Analysis type drop-down list box, Time Domain (Transient) is selected by default.
Accept the default setting.
5. Specify the options required for running a transient analysis. In the Run to time text box,
specify the time as per design (e.g. 1000nS).
6. From the Option, select the simulation category Gate Level Simulation. Select the timing
mode to optimize the propagation delay.
Click OK to save your modifications and to close the dialog box.
