[Libre-soc-dev] Questions about the logos.

[Jean-Paul Chaput]

Hello Staf,

As said in the title, I have some questions about including
the logo:

1. The GDS do not contains the logo drawn in the top metal layer,
   but also all the other metals. I assume it is for density reasons.

2. In additions to those layers, there is a layer Id 150, with
   DATATYPE 1 to 6. What are they for? If they need to be included,
   we must create an associated basic layers in techno.py.

3. Where do I put the logos on the chip. They are all around 150um
   wide, and that do not fit in the spare triangular area in the
   pads corners.

4. Last little drawback : instead of being made a few big polygons,
   the are build of huge amount of tiny rectangles. So at low zoom
   level, even if big, the logo is not drawn at all.
     Not a real problem, but you may need to be aware of it.

Best,
