使用simvision察看ovm内的对象和信号
ovm_set "*" "recording_detail" OVM_FULL -config
ovm_phase -stop_at run
run
probe -create -shm worklib.ovm_pkg:vm_top_levels -depth all
run -clean
savedebug -overwrite
run
exit
仿真结束后使用 simvision -snapshot worklib.debug:sv 提示找不到snapshot file : worklib.debug:sv
snapshot file是生成了的 ，为什么找不到呢，实了多个路径执行simvision -snapshot worklib.debug:sv 都不行，
请问大家遇到过这样的问题没?
看一下log。
非常感激回复啊 。

上面是关键的log信息，红色部分是生成了snapshot file.
worklib所在路径：
INCA_libsirun.lnx86.10.20.ncirun.ncworklib
xxxx-xxxx@login1-161% simvision -snapshot worklib.debug:sv
ippe: 10.20-s128: (c) Copyright 1995-2012 Cadence Design Systems, Inc.
ippe: *F,BADSNP: Unable to open the 'worklib.debug:sv' snapshot file..
报错打不开snapshot file.
ncsim worklib.test:sv -cdslib ../INCA_libs/irun.nc/cds.lib -hdlvar ../INCA_libs/irun.nc/hdl.var或
simviiosn -wave直接打开波形。

借宝地问下，小白一个，这个irun就是跑不出来，log文件如上

请问小编，问题解决了吗?我遇到了相同的问题。我感觉应该是出自UVM/OVM相关部分无法保存，但是我不确定，也不知道如何解决。请小编指点
