EDA for Strategic Radiation Hardened Precision Analog IC Obsolescence Mitigation

ABSTRACT: This proposed program leverages mature semiconductor TCAD and EDA tools. These tools are widespread in modern analog IC design and already possess capabilities applicable to obsolete part replacement. Our plan for detailed R & D activity emphasizes tool adaptations/improvements for simplifying, automating, and accelerating the overall design retargeting task, the application of radhard-by-design, and detailed physics-based simulation of environments particular to Air Force strategic systems. We have developed concepts for prompt dose simulation that are ideal for this program, but need refinement and robust implementation into a commercial toolset. Other adaptations are required at the flow or procedural level, e.g., in addressing obsolescence, one has the benefit of (at least partial) starting design and experimental performance data. This provides opportunities for streamlining the traditional IC design flow. However, the"process retargeting problem"is a complicating factor of obsolescence, but one that can be addressed through R & D applied to TCAD flows and effective use of the pureplay foundry model and process design kits. Our Phase 1 program will produce detailed specifications for tool flow improvements and also demonstrate proof of concepts for new models. In Phase 2 we will implement the framework in a commercial TCAD/EDA flow and demonstrate its use in silicon. BENEFIT: Benefits: Reduced time and cost for replacement of obsolete strategic rad hard parts Commercial Application: There is commercial interest in emerging concepts for reconfigurable analog, analog IP, and design reuse, that attempt to parallel the digital world. The capabilities for efficient retargeting of existing designs into multiple different foundries are also applicable in these areas.
