4.2.2 Preparing the Pin List for Import into OrCAD Capture CIS

  1. Launch Microsoft Excel, and open the *.rpt file that has the exported pin information. Before opening, ensure that All Files (*.*) is the file type as shown in the following figure.

  2. In the Text Import Wizard - Step 1 dialog, select Delimited, start import at page 14 and click Next. The first 14 rows of the spreadsheet have data unrelated to the pin information.

    The following figure shows the Text Import Wizard with the Delimited option selected and the Start Import at Page option having the value 14.

  6. Add the following headings for the columns. See Figure 4-19.

    • Number
    • Name

    • Type

    • Pin Visibility

    • Shape

    • Pin Group

    • Position

    • Section

    By default Number, Name and Type columns are populated from the report. For Type, Shape, Position, and Section columns, add information manually to avoid warnings from the OrCAD Capture tool.

  7. For Type column, choose and type one of the following options:

    • 3-State
    • Bidirectional

    • Input

    • Open Collector

    • Open Emitter

    • Output

    • Passive (Unused pins like DNC or NC)

    • Power (Supply and ground pins)

  8. Leave the Pin Visibility column blank. The check boxes are automatically populated in the New Part Creation dialog.

  9. In the Shape column, enter one of the following shapes according to the requirement:

    • Clock
    • Dot

    • Dot-Clock

    • Line

    • Short Clock

    • Short Dot

    • Short Dot Clock

    • Short

    • Zero Length

    The default shape for most of the FPGA symbol pins is the LINE.

  10. Leave the Pin Group column blank.

  11. In the Position column, enter one of the following positions according to the requirement:

    • Bottom
    • Left

    • Right

    • Top

  12. In the Section column, enter either a number or an alphabet based on the selection made for the Part Numbering option. OrCAD Capture supports two Part Numbering options, that is, 1, 2, 3, 4,… for Numeric option and A, B, C, D… for Alphabetical option.

  13. Save the Excel file with an appropriate name.
