In the release notes for quartus 15 (
https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/rn/rn_qts_dev_support_update.pdf ) it mentions this problem: "Fixes an issue that causes the Storage Qualifier feature of the SignalTap™ II Logic Analyzer to miss samples." I'm not sure if there is a work around for 14.1 but, as with many issues, it looks like the fix is to upgrade to quartus.

Hi niccur,
Thanks for you information.
It's very strange, the same project can work well in QII12.1.
BTW, I update from 12.1 to 14.1 and encounter this issue. Then i update to 15.0, the issue still happens.
