Early Power Estimators (EPE) and Power Analyzer - Estimate power consumption from early design concept through design implementation. Designers should use Power and Thermal Calculator (PTC) or Early Power Estimators (EPE) in the initial design stage. Design Pages {"title":"Early Power Estimators (EPE) and Power Analyzer"} Introduction Estimate power consumption from early design concept through design implementation. Designers should use Early Power Estimators (EPE), Power and Thermal Calculator (PTC) or Power and Thermal Analyzer (PTA) in the initial design stages. Power analysis features from that include Early Power Estimators, Power and Thermal Calculator (PTC), Power and Thermal Analyzer (PTA), and the Quartus® Power Analyzer give you the ability to estimate power consumption, as shown in Figure 1. As you provide more details about your design characteristics, estimation accuracy is improved from early design concept through design implementation. Introduction Figure 1. Power analysis from design concept through design implementation. Agilex® and Stratix® 10 FPGA Devices The Agilex® and Stratix® 10 FPGA Power and Thermal Calculator (PTC) and Power and Thermal Analyzer (PTA) are integrated with the Quartus® Prime Design Software. You can access the PTC and PTA from the Tools menu in the Quartus Prime Design Software, or by running the quartus_ptc command in your command shell. For the convenience of designers who may be working only on power estimation and not running design compilations with the Quartus Prime Software, a stand-alone version of the PTC and PTA are also available. The stand-alone version offers all the same features as the version integrated within the Quartus Prime Software. You can calculate field-programmable gate power consumption for Agilex and Stratix 10 devices using the PTC or PTA, and for more accurate power estimation, use the Power Analyzer in the Quartus Prime Software. Altera recommends that you switch from the PTC or PTA to the Power Analyzer once your design is available. The Power Analyzer produces more accurate results because it has more detailed information about your design, including routing and configuration information about each of the resources in your design. You should treat the PTC and PTA results as an estimate of power, not as a specification. You must verify the actual power consumption during device operation because the information is sensitive to the actual device and design input signals. Download the Power and Thermal Calculator or Power and Thermal Analyzer Download Stand-Alone PTC Tools The older Power and Thermal Calculator tool is downloadable from the Quartus® Prime Design Software Download pages from 25.1.1 or earlier. You can download the stand-alone PTC tool from the Download Center Select 25.1.1 version or earlier of Quartus Prime Pro Software Select your “Operating System” In the page, click on the “Individual Files” tab Scroll down to “Power Thermal Calculator” in the “Add-On and Stand-Alone Software” section Click on download Review the PTC User Guide Download Stand-Alone PTA Tools The Power and Thermal Analyzer (PTA) is the current tool. Review the PTA features and documentation Access the stand-alone download for the Windows or Linux version from this page also. Review the PTA User Guide Download the Power and Thermal Calculator or Power and Thermal Analyzer Download Early Power Estimators Altera® FPGA families with links to respective Early Power Estimator (EPE) worksheets. If you already have design files or a project set up in the Quartus Prime Software, you can have the software generate data to automatically populate the worksheets. During implementation, you can refine your power estimates using the Power Analyzer tool in the Quartus Prime Software.

For example, if you use the Quartus Development Software v13.1 to generate the EPE file, you must use the EPE worksheet version 13.1. The 19.4 version of the Stratix 10 Device Early Power Estimator is the final release of this tool. Starting 20.1 release, it is replaced by the new FPGA Power and Thermal Calculator, which supports both Stratix 10 and Agilex devices. The FPGA Power and Thermal Calculator is available either integrated within the Quartus Prime Software or as a stand-alone version. The stand-alone version is available for download from the Download Center for FPGA page under the Add-On and Stand-Alone Software in the Individual Files tab. For Stratix 10 devices, recommends using the FPGA Power and Thermal Calculator as it uses the latest power models. The download link for 19.4 Stratix 10 FPGA Early Power Estimator (EPE) will be removed at a future date. For Legacy Device Families – please visit the respective Legacy Device Support Collections . Known issues for Early Power Estimator (EPE) tools Collapse All Expand All Known issues for Early Power Estimator (EPE) tools Microsoft has released an update to fix this issue, please go to the corresponding Microsoft Support Page based on your Excel version: · Excel 2013*: https://support.microsoft.com/en-us/kb/2920754 If the above update doesn't fix the issue, or if you do not have access to these updates, try the following workaround steps: 1.
