    • My Favorites (What is 'My Favorites'?)
      'My Favorites' is a special kind of lens which you can use to bookmark modules and collections directly in Connexions. 'My Favorites' can only be seen by you, and collections saved in 'My Favorites' can remember the last module you were on. You need a Connexions account to use 'My Favorites'.

      Definition of a lens

      Lenses

      A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

      What is in a lens?

      Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

      Who can create a lens?

      Any individual Connexions member, a community, or a respected organization.

      What are tags? tag icon

      Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

Starting a New Schematic Entry in OrCAD Capture

Module by: Patrick Frantz

Summary: Starting a schematic entry in OrCAD.

Warning:

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 http://cnx.rice.edu. Click on the 'Contents' tab and select Rice University ELEC 424/427 under the 'Courses' tab.

Before You Begin

It is helpful to be very organized when you are designing. OrCAD will create many files and if you keep all of them in the same directory, it can quickly become very confusing. I like to make a directory hierarchy and put associated files into subdirectories. Before beginning, navigate to the directory in which you will keep your project and create the following subdirectories:

  • sch - for your schematics.
  • lib - for symbol and footprint libraries.
  • board - for your board files.
  • comps - for component datasheets.
  • assy - for assembly related documents.
For larger designs, more subdirectories would be desirable, but these will be sufficient for this project.

Starting a New Schematic Entry

To create a new project, first start OrCAD Capture and click File-->New-->Project. You will see the following dialog box.

Browse to the sch directory that you created and name the project Elec424Tutorial. You now have an empty project workspace. You should see an empty schematic page and a project window like the following.
