A step-by-step tutorial to learn how to do a schematic entry in OrCAD.
The Connexions version of the OrCAD tutorial is still in development. Please click here for the original and complete tutorial. You may also browse this complete tutorial within Connexions by using the Mozilla browser and accessing the main Connexions page at (External Link) . Click on the 'Contents' tab and select Rice University ELEC 424/427 under the 'Courses' tab.

Setting up the environment

Now that you have your parts library set up, you are ready to begin entering schematics. You can see from the project window that you already have one page of schematics called PAGE1 in a folder called SCHEMATIC1 . If you can’t see this, click on the ‘ + ’ next to the dsn file to expand the view. Even though our circuit is small enough to fit on one page, we will use two pages to demonstrate a schematic with multiple pages. First add a new schematic page by right-clicking the schematic root folderand selecting New Page . You will be prompted to provide a name for this page. Call it Page 1 – Power and Connectors . Now rename the original page by right-clicking and selecting Rename . Call this Page 2 – Xilinx PLD . It is always nice to give your schematic pages useful names. While you are at it, rename the schematic folder in the same manner, calling it Elec424Tutorial .

Open page 1 of your schematics by double-clicking it in the project window. This will bring up a blank page. Before we place parts, let’s do a couple of things. First, I like to make the page size a bit bigger than the default. You can fit a lot more onto the page and it will still look nice when printed. To do thisselect Options-->Schematic Page Properties… Click the Custom radio button and use the following values (width=15.2, height=11.5). Second, there is a title block in the lower right corner. We are going to replace this with our own, so highlight the title block and delete it. We add a new title blockby selecting Place-->Title Block… You will see the following dialog box.

The title block is in your library, so we need to add that to the list of libraries. Click the Add Library button to browse to and select the library you created for the tutorial. Once you have added the library, you will be able to choose the RiceTitleBlock to add it to your design. Place the title block in the lower right corner of your schematic page. The title block has fields to put information for each page of schematics. Double-click the text to edit each fieldand change the information on each page so that it looks something like this.

Placing parts and making connections

You are now ready to start placing the electrical components for your design. Open the first page of your schematics and click the Place Part icon on the toolbar on the right side of the screen. You will then get a dialog for choosing which part you want to place on your schematics.

Place Part Dialog

Select the part CONN JACK PWR and click OK . Place the part on the left side of your schematic page. Now place the remaining parts on both pages using the attached completed schematics as a guide. A PDF file of the schematics can also be found on Owlnet.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
