Why does the Power Thermal Analyzer tool display device family compatibility errors when opening files from different device families in Quartus® Prime Pro Edition Software version 25.3? - Why does the Power Thermal Analyzer tool display device family compatibility errors when opening files from different device families in Quartus® Prime Pro Edition Software version 25.3? Description Due to a problem in Quartus® Prime Pro Edition Software version 25.3, during a single session, if a new Power Thermal Analyzer (PTA) design file is created targeting a specific device family, all subsequent PTA design files opened will be loaded targeting the same device family. This occurs regardless of the actual target device defined in those files. This problem occurs when switching between Stratix™ 10 FPGA and Agilex™ FPGA device families within the same session. For example, if you first create a PTA file for a Stratix™ 10 FPGA device and then open a PTA file meant for an Agilex™ 7 FPGA device, the Agilex™ 7 FPGA file will incorrectly be loaded as targeting the Stratix™ 10 device. This results in the error: " Error (25383): The Stratix™ 10 PTA does not currently support opening files created by the Agilex™ 7 PTA. Import canceled. " The same issue occurs in reverse when opening Stratix™ 10 FPGA PTA files after creating an Agilex™ FPGA PTA file. Resolution You can avoid this issue using one of the following methods: Close and reopen Quartus® Prime Pro Edition Software before opening PTA files from different device families. This method works when PTA is launched from Quartus® Prime Pro Edition Software; for standalone PTA, closing and reopening PTA before opening different device family files is more appropriate. Create a new PTA file using the target device family, then open the desired file from the recently created PTA file. Use the open_design_file Tcl command by copying the equivalent Tcl command displayed in the Tcl Console and modifying it to replace the target device family in the -family parameter to match the desired device family. This problem will be fixed in a future version of the Quartus® Prime Pro Edition Software.
