3D layer information for techeditor necessary

[GoogleCodeExporter]

The request is two-fold

1.) some layers in certain technologies are not defined sequently. Means, MET3 
can have a lower GDS layer-number than MET1. Since Toped sort its layers 
corresponding to GDS-number the design-view leads to some irritation when e.g. 
MET1 covers MET3.

2.) in the planned 3D-view the data needed anyway ;)

Two parameters should be sufficient:
height: defines the distance between the bottom surface of a layer to the buld 
surface
thickness: defines the thickness of the layer

e.g.: M1: height = 800um, thick = 400um
      p+-well: height = -1000um, thick = 1000um

Because of the height definitions the layer can be sorted in the OpenGL view 
properly. Also an additional sort button (sort for GDS-nb. or sort for height) 
in the sidebar could facilitate the viewing.

Still not accepted?

let me bump it again ..

Nice graphical outputs (at least if we compare to Cadence Virtuoso layouts) are 
basically a result of alpha-blending and alpha-blending is working best with 
solid fill-styles. At least in such a configuration the layer deepness should 
be of interest if we do not want have these effects as described above (again: 
Met1 covers Met3, PIMP covers MET1, etc.).

In this point of view Cadence need not to be copied.

What is your opinion?

best
armin

p.s.: please check also the latest layer setup for the MOSIS process ..

I have no argument against this whatsoever. "New" status doesn't mean "not 
accepted" - :) I've changed the status anyway.
