FPGA Database Wizard

The FPGA database wizard guides you through the steps necessary in order to specify the information required to build a new FPGA database in PADS I/O Designer.

1. Do one of the following to invoke the FPGA database wizard:

• Select File > Add to Board > New FPGA from Wizard.

• Right-click in the project window and select Add to Board > New FPGA from Wizard.

2. Specify a name (for example, MyFpga) and location for the new FPGA database and click Save. PADS I/O Designer displays the Start page.

3. Click Next to display the Signals Source page.

4. Specify the type of source file and the file path:

• VHDL: This is the file that is analyzed by PADS I/O Designer and from which signals are read. If the file contains multiple top-level units, you are asked to choose one of them.

• Verilog: If you have a Verilog file that references some external files, you are asked to enter the directory in which to search for those additional files. See "Additional HDL Files" for more information.

• Spreadsheet: If you specify this option, you are asked to specify the type of delimiter.

5. Click Next.

6. If necessary, specify additional source file data and click Next to display the Vendor and Device page.

7. Specify vendor, device, and default I/O standards for use in the new database.

You can select one of over 5000 devices from a library that is kept current with those of the FPGA vendors.

8. Click Next to display the Place and Route page.

9. Specify the Place & Route constraints file and the Place & Route pin report file. You can also specify additional data exchange files on this page.

See “Place and Route Constraints Files” and “Pin Report Files”.

10. Click Next to display the Synthesis page.

11. Specify the tool name from the drop-down list and specify the Synthesis constraints file. See “Synthesis Constraints Files”.

12. Click Next to display the PCB Flow page.

13. Specify a unique part number in the Part number field.

Note
	For OrCAD flows, specify additional information (EDIF file).

14. Specify a cell name.

15. Click Next to display the Finish page. This page provides a summary of the settings as shown in Figure 6-1.

16. Click Finish to close the wizard.
