Logotype/Graphical design on layout

[krippkrupp]

When reading the Pulpino datsheet, I noticed that the authors had made a graphical logotype on the layout using cell placement.

Is there an neat way to do this in SoC encounter during place and route? My thinking is that I can calculate the specific coordinates to describe my logotype and then set the placement density on the board according to the coordinates? Is there a better way to achieve this?

Thank you in advance!

density screens are the easiest way. you can programmatically declare them in TCL

Thank you!
Do you know of an easy way to convert a bitmap file to a density screen?

long time ago, I created a TCL script to generates the def file to be imported in Innovus.
For the density, I relied on a graphical tool to transform a picture into black and white, or gray and used this value to create a more or less square block in the def file in each sub-"pixel".
