You may see this error when using Microsoft Office Excel 2010 32-bit to open the 32-bit Early Power Estimator (EPE) version 12.0sp1. This issue was caused by a bug in the EPE when version 12.0sp1 was first released. This issue affects the following EPEs:
- Stratix® III, Stratix IV, Stratix V, Hardcopy® III and HardCopy IV PowerPlay Early Power Estimator
- Cyclone® III, Cyclone IV and Cyclone V PowerPlay Early Power Estimator
- Arria® II GX, Arria II GZ, and Arria V PowerPlay Early Power Estimator
Version 12.0sp1 of the EPEs are now updated with the fix that resolves the issue. If you are seeing this error, you may have downloaded the EPE before the fixed versions were available. You will need to re-download the EPE from PowerPlay Early Power Estimators (EPE) and Power Analyzer.
