It should be mentioned that the underlying reason for having James and his group do the standard cells for GlobalFoundries GF180MCU is that Global contracts out to ARM for a lot of its IP, so most of the useful IP for the process belongs to ARM and is not part of the set of libraries that Google was given by GF to open source. The IP that was given to Google was all IP that was developed by GF itself. The ARM IP included all the "mainstream" libraries, whereas the libraries GF made were more "niche" libraries. So we got padframe I/O cells and standard cells that are all in the 5V domain, and nothing in the 3.3V domain. So James is filling a much-needed gap in the open source IP offering for GF180MCU.
