-The Google-Skywater project is a collaboration between the Skywater Foundry and Google's open source EDA efforts.
+====== Open MPW Program ======
+The Open MPW program was a project by Google which provided free manufacturing of chips to open source projects. The actual management was done by Efabless.
+Their where;
+  * 8 open MPW runs on Skywater's SKY130 process technology (https://github.com/google/skywater-pdk)
+  * 2 open MPW runs on GlobalFoundries GF180MCU process technology (https://github.com/google/gf180mcu-pdk).

+====== Reading Efabless ID Numbers ======
-A number of pages are listed under vendor "efabless". For example
+Most Efabless parts have ID numbers embedded in their design. This ID number can be read via the Caravel SoC and is also found on the top metal.

+ID number is in the bottom-left corner of the die.
+The ID number where originally connected to the position in the reticle (case for SKY130 MPW1, MPW2, MPW3) but then changed format.
+For chipIgnite dice the first 4 hex digits are the 2-digit year, and 2-digit month (e.g. 2306 for the CI2306 shuttle), and the last 4 digits are a random hex value for the respective die/project. This 8-digit "project ID" was generated when the repo was first created on the Efabless servers... when the customer had finished their design, it would be placed into the next available reticle slot.
