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.

An adaptive mesh of virtual nodes is provided to analyze the performance of a power/ground plane pair having an irregular shape. Plane transmission line characteristics and regional modal resonances can be modeled accurately, and with a significant decrease in simulation time as compared to traditional methods. A variable-sized cell structure is constructed with smaller cells in irregular regions and with larger cells in uniform regions. Grid nodes may thus stay aligned along length and width to allow parameters of equivalent circuit models to be scaled appropriate to the cell size.
