Hello,

I think, that the new Signaltap version basically offers improvements, although I wasn't able yet to evaluate them in detail. But it's also true, that the segmented acquisition mode can't be used any more if LE resources are low. For the particular design, I'll stay with V7.1. Usually, I keep several previous Quartus versions in my development enviroment cause synthesis results sometimes are different.

Another thing to note is that an STP file created in 7.2 can be used in 7.1. When migrating back, most of the setup options will remain intact. When opening up the file in the older release, SignalTap will prompt you to "upgrade" the file.

I also think, this should be possible but don't see yet, how to achieve it. With V7.1 I just get an error message: "...You must use a newer version of the Quartus II software to open this file".

Best Regards,
