Thank you first. I find one solution to debug this error today:

:-P Solution: In Qsys, ssram & CFI Flash will be transfer to 'Generic Tri-state Controller', so i just need add two 'Generic Tri-state Controller' (ssram_controller、flash_controller) to control external ssram&Flash. Surely, i also need "Tri-state Conduit Pin Sharer" & "Tri-state Conduit Bridge". Definitely, compare with SOPC Builder, Qsys can increase the fmax (i have use Qsys 1year, Quartus 10.1 & 11.0), decrease the LEs Usage. If you interest in Qsys's application, you can search my academic paper "Using NOC technology to improve Photoelectric Encoder system for LAMOST spectroscopes" (IEEE ASICON 2011, IEEE Xplorer).
