A shuttle service is the same as a multi project wafer.

On 30th June 2020, Tim Ansell announced the collaboration between Google and Skywater to provide a free shuttle service in his FOSSI dialup talk.

These slides taken from his talk show the overview:

Chip Foundry Shuttle

Normally in an MPW you would have the whole die to yourself. In the ChipFoundry Shuttle all the designs will be within the user project area of the Caravel harness.

Caravel has its own RISCV processor and a neat datasheet. The idea here is to make it easier to bring up and debug your designs at the cost of some area.

Read this post to find out what you could fit in the user space.

The Google shuttle returned chips in type of packaging called Wafer Level Chip Scale Packaging and then the easier to handle QFN.

Course feedback

After a long wait, I finally got the chance to take the Zero to ASIC Analog Course, and it’s fantastic! The comprehensive curriculum covers everything from schematic capture to GDS file generation, offering a deep understanding of the entire design process, along with plenty of debugging opportunities. I highly recommend that every Analog Design Engineer acquire these skills to become a full-stack developer in this complex yet fascinating field.
