你好,我想再咨询你下,TEST-T> analyze_faults U_pad/U_TESTMODE/PS -stuck 1 ------------------------------------------------------------------------------
Fault analysis performed for U_pad/U_TESTMODE/PS stuck at 1 (input 1 of TSD gate 4546).
Current fault classification = AN (atpg_untestable-not_detected).
------------------------------------------------------------------------------
Connection data: to=REGPO,CLKPO,MASTER,SHADOW,TIEX,TLA,CLOCK,SET,RESET,TS_ENABLE
Fault site control to 0 was successful (data placed in parallel pattern 0).
Observe_pt=any test generation was unsuccessful due to atpg_untestable.
Observe_pt=4546(TSD) test generation was successful (data placed in parallel pattern 1).
Observe_pt=4548(BUS) test generation was unsuccessful due to atpg_untestable.
比如PS已经被 tied 0了,我现在用analyze_faults U_pad/U_TESTMODE/PS -stuck 1, “ Observe_pt=any test generation was unsuccessful due to atpg_untestable” 为什么报这个?“ Observe_pt=4548(BUS) test generation was unsuccessful due to atpg_untestable” 还有为什么会跟4548这个有关系?
