Ballast: Implementation of a Large MP-SoC on 22nm ASIC Technology

Abstract

Chips have become the critical asset of the technology, and increasing effort is put to design System-on-Chips (SoC) faster and more affordable. Typically the focus of the research has been on the Power, Performance and Area optimization of the specific component or sub-system. To improve the situation we report design effort for complex SoC counted from specification to ASIC tape-out to lay out a solid reference for the community. Ballast is the first SoC-Hub chip taped out on 22nm technology. It includes six sub-systems on 15 mm2area and reaches 1.2GHz top speed. The design team included 24 persons and spent 21 200 person hours to tape-out in one calendar year from scratch. This is an outstanding achievement and sets the baseline to SoC design productivity development.
