Self-HEALing mixed-signal Integrated Circuits (HEALICs)
Abstract
The goal of the Self-HEALing mixed-signal Integrated Circuits (HEALICs) program is to develop technologies to autonomously maximize the number of fully operational mixed-signal systems-on-a-chip (SoC) per wafer that meet all performance goals in the presence of extreme process technology variations, environmental conditions, and aging. Virtually all DoD systems employ mixed-signal circuits for functions such as communications, radar, navigation, sensing, high-speed image and video processing. A self-healing integrated circuit is defined as a design that is able to sense undesired circuit/system behaviors and correct them automatically. As semiconductor process technologies are being scaled to even smaller transistor dimensions, there is a dramatic increase in intra-wafer and inter-die process variations, which have a direct impact on realized circuit performance, as well as significantly increased sensitivity to temperature and ageing effects. This applied research program aims to develop techniques to regain lost performance and stabilize operation of mixed-signal SoCs over system lifetimes. Consequently, the long-term reliability of DoD electronic systems is expected to be significantly enhanced.
