Description
Due to a problem in the Intel® Quartus® Prime Pro Edition software version 19.4 and earlier, after unarchiving your project, you may see errors while trying to migrate custom components to a newer version of the Intel® Quartus® Prime Pro Edition software.
Resolution
To work around this problem, in the original version of the Intel® Quartus® Prime project, explicitly add the custom component hw.tcl file to the project files and then perform the archiving process. After this, open the Intel® Quartus® Prime Archive File (.qar) in the newer version of the Intel® Quartus® Prime Pro Edition software and perform the upgrade process.
