I use GDSII file from Silicon Ensemble. Now I know that this GDSII it is "layout does not include standard cells".
When I've put this file in Cadence CIW ( Import - Stream ) I've obtained warning : " (setup file ) - scale was not float " and nothing else.
I've tested a lot of possibilites ( UU/DBU ) - No effect..

PS. When I've put DEF file from SE everything was ok, but when I've tried Export Stream , problem has come back ....
PS. Main obiective : Put "full" GDSII to Calibre DRC, because GDSII from SE doesn't work.
Before importing, you should have standard cells layout in CIW that have name correspond to you LEF in SE.
When you Import->Stream, add option retain library definition.
This option will search the cell name in CIW that match with the cell name from SE and use that cell in CIW as a standard cell.
Hope it could solve your problem.

I think SE only exports metal, via and cell outline....
# example of SE script
# gds2 out
#
OUTPUT GDSII MAPFILE "gds2.map" LIBNAME "top" STRUCTURENAME "top" FILE "top.gds" REPORTFILE "gds2out.jnl" UNITS Thousands ;
Just make sure your mapfile and units are correct, then import the gds
with standard cell libary as well.
