Self-HEALing mixed-signal Integrated Circuits (HEALICs)
Abstract
(U)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. This program is an outgrowth of mixed signal development in the Design Tools for 3-Dimensional Integrated Circuit program. 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. The motivation for this program came from findings under the TRUST program that, as semiconductor process technologies are being scaled to even smaller transistor dimensions, there is an exponential increase in intra-wafer and inter-die process variations, which have a direct impact on realized circuit performance manifested as significantly reduced yields of fabricated fully operational SoC. The core goal of the HEALICs program is to regain this lost performance. Additionally, the technology developed under this program is expected to address environmental variations and aging as well. Consequently, the long-term reliability of DoD electronic systems is expected to be significantly enhanced.
