When using Microsoft Excel 2007 and the Early Power Estimator (EPE), you cannot select a Cyclone® IV device when you first open the EPE. If you change the family from Cyclone III (default family setting) to Cyclone IV, the devices in the drop-down menu still shows Cyclone III devices.
To select a Cyclone IV device, you must enable macros, by following these steps:
- Just below the Excel toolbar, on the left side of the page, a message window appears with the warning Security Warning Some active content has been disabled. Click on the Options... box to the right of the warning.
- Select Enable this content.
- Click OK.
After enabling macros, you can select a Cyclone IV device in the drop-down menu.
All Altera EPEs must have macros enabled for the EPE to operate correctly. This applies to all versions of Excel.
