Imec in Belgium has started a research programme into using chiplets in automotive designs.

"Right now automotive is probably the biggest transformation happening with more eco friendly, safer and customisable vehicles," said Kurt Herremans, programme manager at imec, at the TSMC open innovation partnership meeting in Amsterdam today.

"There is electrification and the growth of autonomy with ADAS and the promise of autonomous vehicles but also the move from hardware to software defined vehicles. These key transformations require innovation in electronics," he said.

This needs scalable, flexible architectures that are also reliable, says Herreman, and chiplets are a key approach that is already being proven in data centre and high end consumer designs. However this will require new standards and may require new certification as well.

Imec has started the automotive chiplet programme to build some prototypes to measure the failure modes and this is currently in definition. "The bridges and interposers used for chiplet implementations are all additional failure modes, and what can imec do to research these to come up with new solutions," he said.

Using chiplets can provide a scalable architecture from Level 2 ADAS up to Level 5 full autonomy with over 2000TOPS of performance by adding in additional chiplets, but there needs to be software compatibility, he says.

"This would need to be scalable from the L2 entry car to L5 with the same architecture for software reuse and that helps reduce the development cost," he said.
