Occasional ContributorPower Analyzer
Hello,
I tried to follow the process of Early Power Estimators (EPE) for power analysis, but it shows no memory left.
Best Regards,
Shweta Sawant
Also, all the bank in the given FPGA re 3.3V but here it shows 3V for 2 banks. Is there any chance that we can change it?

Can you provide more info? Not clear what the issue is.
Shweta_sawantI am geeting error of low: user Provided insufficient toggle rate. What should I do??? any refrence documents. It's on priority
- sstrellSo that’s the power analyzer, not the EPE. The low confidence metric is because you haven’t provided enough information to get an accurate analysis including signal toggle rates. See this training: https://cdrdv2.intel.com/v1/dl/getContent/653116

where can I find .saf file for Intel Quartus prime Lite edition 17.0.

Hi Shweta_sawant,
It seems the .saf file can not be generated by 17.0 version, according to this link below.

How to generate the .saf File? I tried many methods. Please reply to all the questions

I have downloaded 19.1 version .. how do I generate the .saf file?

I get this error message continuously . What should I do?

Hi Shweta_sawant,
Have you input any Signal Activity Data? If you didn't input the Simulation results etc, the power analyzer does not know the toggle rate, therefore saying confidence level is low.
Please check the "1.4.2 Sources for Signal Activity Data" Chapter in Intel® Quartus® Prime Standard Edition User Guide: Power Analysis and Optimization: https://www.intel.com/content/www/us/en/docs/programmable/683506/18-1/sources-for-signal-activity-data.html
If you do not require a estimation result with a very high accuracy, you may simply use EPE tool to estimate the power consumption.
Since you already have a project in Quartus ,you can export the EPE file (<revision name> _early_pwr.csv) generated by the Intel® Quartus® Prime software and import it to the EPE spreadsheet to check the estimation result.
The EPE tool and UG can be downloaded from this page:
