请问各位前辈
当我做到 Specify Scan Chain 时
键入指令後，出现以下讯息
Tracing scan chain: scan1
**WARN: (SOCSC-1205): FORWARD - Tracing stopped at instance
core/TopAppAccess1/ShiftRegister/U52.
**WARN: (SOCSC-1205): FORWARD - Tracing stopped at instance
core/TopRMem1/MinToR1/RSeqOut4/U58.
**WARN: (SOCSC-1205): FORWARD - Tracing stopped at instance
core/TopRMem1/MinToR1/RSeqOut3/U57.
Failed to trace scan group scan1 (0 elements).
*** Scan Trace Summary:
**WARN: (SOCSC-1104): Failed to trace scan group scan1 (0 elements). Use
'scanTrace -verbose' to see the results of scan tracing.
INFO: Failed to trace 1 scan group .
停止的地方都是同一种 cell，如连结

请问这是什麽问题？是否有解决的方法？谢谢大家
