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?
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".
