Self-HEALing mixed-signal Integrated Circuits (HEALICs)
Abstract
Virtually all DoD systems employ mixed-signal circuits for functions such as communications, radar, navigation, sensing, and 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 intra-die process variations, which has a direct impact on yield and realized circuit performance, including significantly increased sensitivity to temperature and aging effects. The Self-HEALing mixed-signal Integrated Circuits (HEALICs) program developed 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, and to sustain circuit performance in the field in the face of changing environmental conditions and component aging. This applied research program developed techniques to regain lost performance and stabilize operation of mixed-signal SoCs over system lifetimes. Consequently, the long-term reliability and performance of DoD electronic systems may be enhanced.
