help:Import layout(GDSII) into ADS

I make the spiral inductor layout in virtuoso, and i need import the layout
into @DS-momentum in pc.
I outport the layout from cadence into GDSII , but @DS doesn`t identify the GDSII file when imported into @DS.

how can i figure it out ?

By the way i want to use momentum in ADS to model spiral inductor.
Does anyone have some experience in it ?can you give me some suggestion?

thank in advance! any suggestion will be appreciate!
