Abstract: The present invention discloses a method for accelerated solving of large sparse matrix, system and storage medium thereof, which falls into the technical field of electromagnetic field computation. In view of the problem that solving of the current large sparse matrix is slow and not accurate enough, the present invention provides a method for accelerated solving of large sparse matrix, comprising: restoring connection relationships between port nodes of an initial finite element matrix, and obtaining restored second-order finite element matrix; converting the second-order finite element matrix to an undirected graph; decomposing the undirected graph, and selecting optimal decomposition via an evaluation function; renumbering nodes of the second-order finite element matrix according to the renumbered nodes and generating a new final finite element matrix; and solving the final finite element matrix.

Abstract: A method for real-time extraction of on-chip simulation information including acquiring simulation job information, and analyzing the simulation job information to obtain option and parameter information; and acquiring index information from a simulation project according to the option and the parameter information, and formatting the index information to obtain a simulation result. According to said method, key information of a simulation result is extracted in real time by performing text scanning and pattern analysis on a log file during a simulation process, so that a user can conveniently learn about the progress situation of the current simulation task at any time, and determine to continue or terminate the task at any time according to the current state and result situation, thereby more flexibly controlling a flow according to an actual situation, simplifying operations, increasing design efficiency, and compensating for the disadvantages of traditional simulation methods.
