layer num & layer ID

hi2yogi

I am checking layer ID in a layout data base with following command.

cv~>lpps~>layerHeader~>lpps~>layerNum

or

cv~>layerHeaders~>lpps~>layerNum

or

cv~>shapes~>layerNum

But it is not giving layer id as in *_Tech.layermap file.

i.e.  for  M2 pin & M2 drawing above command giving 15 15 , but in tech file  M2 pin  ..layer id is 17  32 &  for M2 drawing  layer id is 17 0.

please suggest me right way to check that ...

    I understand your explination. I need help in that case...

    1)  how i should find out  database layer numbers and purpose numbers  ?

    2)  how i should ensure that it (database layer numbers and purpose numbers)  exist in techlayermap

    ie let suppose i have ported layout data base from 32nm to 28nm then i would like to ensure  that there is no unkown layer ( layers which does not support by 28nm)

    Please help me with above !!!!!!

    Once again thanks for time
