Hi Steve,
We are just getting into this ourselves. But have you clipped the
constraint areas. Also, have you exported the constraints from CM
and imported them into the module?
There are just my thoughts, I have not applied them yet.

Subject: [PCB_FORUM] Design Reuse From Existing Designs
I am creating a module from an existing design. I have done the following:
1, Read in the tec file from the existing board and imported it to the
Module.
2, Read in the new tel file to the module.
3, Took existing (board I want to copy from) and exported the placement.
4, Read the placement into the module, that placed only the components I
needed for the module.
5, Clipped all the traces, vias and fills from existing board from specific
area.
6, Imported clip files to the module.
Now I notice all the traces are missing properties. I am necking down inside
fine pitch BGA's and I have a ton of trace width errors. Does anyone know
how to import the net properties to my existing module?
I tried reading in the netlist with properties but not sure this is the best
way?
Thanks
Steve
