Can I open an SignalTap File (.stp) that was created in a previous version of the Quartus® II software?

Description

Yes, you can open an old STP file in a current version of the Quartus^® II software. However, opening an STP file modifies it so that it cannot be opened in a previous version of the Quartus II software.

For more information on using the SignalTap II logic analyzer, refer to the Design Debugging Using the SignalTap II Embedded Logic Analyzer chapter in volume 3 of the Quartus II Handbook.
