Working with ILMs

Hi guys,

First,thanks for all your help with my recent questions.

I am trying to work with ILM in my top level, using cadence flow (i am not working in MCMM mode):

in my block level i do: 

createInterfaceLogic -hold -dir ../outputs/my_block.ILM 

the ILM created succesfully.

Than in  top level, i write:

specifyIlm -cell my_block -dir ../outputs/my_block.ILM

and when i try placeDesign, i am getting n error that i didnt imported the ILM.

what am i doing wrong?

if I have multiple cells using this ILM should i run "specifyIlm" for each one?

Thanks!
