3 results about "Subsystem design" patented technology

The application belongs to the technical field of processors, and particularly relates to a selection and subsystem design method, system and storage medium for SRAM. The selection and subsystem design method comprises the following steps: obtaining system specification information of a target processor storage system, analyzing the system specification information to generate a corresponding access model and a hard constraint set; screening SRAM macros that meet the hard constraint set from a preset storage compiler or PDK macro library, and then simulating and rescreening the screened SRAM macros through the access model, and standardizing macro-level features of the rescreened SRAM macros; matching SRAM macros from an SRAM macro candidate set based on bandwidth requirements and concurrent access requirements in the system specification information, and automatically generating multiple groups of SRAM subsystem topology candidates. Compared with the prior art, the application can realize rapid landing, stable signing and production reuse of the SRAM subsystem.

The invention discloses a deep space exploration task forward collaborative design method, and belongs to the technical field of deep space exploration. According to the method, on the basis of a MagicGrid methodology and in combination with a SysML modeling language, a'concept-problem-scheme 'three-level incremental iterative modeling framework is constructed, and full-process digital collaboration from task analysis to subsystem design is achieved. Through four-pillar linkage of demands, behaviors, structures and parameters, automatic association of model elements and design traceability are ensured, and demand verification efficiency and design consistency are significantly improved. Meanwhile, FMEA reliability analysis is embedded into a design process, model issuing, subsystem design and integration processes are standardized in collaborative development, and internal and external division cooperation is supported. According to the method, a standardized and reusable forward design solution is provided for a complex spacecraft system, and the method has high engineering popularization value.
