Why I can't change the device family in Power and Thermal Analyzer?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 26.1, you may not be able to change to a different device family in Power and Thermal Analyzer (PTA) after you create or open a design. For example, if you open a design targeting a Stratix® 10 device, you may not be able to change to an Agilex® FPGA device.

In version 26.1, if you select File > New File to create a new PTA design, the new file wizard does not appear. Without the wizard, you cannot select a different device family when creating a new file.

Resolution

PTA locks a design to the device family selected when the file is created. To explore power consumption across different device families, create a new PTA file in the target family and import your existing design.

To import an existing PTA design into a different device family:

1. Create a new PTA file targeting the desired device family.
2. Use the Import function to bring your existing PTA design into the new file.

If you chose the wrong device family when creating a file, close the existing file and create a new one. In the File menu, select New File, and select the correct device family in the new file wizard.

In version 26.1 of Power and Thermal Analyzer, the new file wizard does not appear when you select New File. To work around this issue, exit and restart PTA. After restarting, select File > New File to open the new file wizard and select the correct device family.
