Patent number: 12581913Abstract: Methods and systems for improved simulation of thermal characterization and thermal modeling of devices, such as smart phones, are described. In one embodiment, a method can characterize center, edge, and corner thermal decay behavior at different locations on a simulated IC. For each location, near and far field thermal effects are captured at the same time. A simulation system can generate a steady state thermal decay curve for each selected location that shows how the temperature changes with distance to a heat source. The system can then use a set of location dependent thermal decay curves to compute, based on an inputted power profile for the IC, a steady state thermal profile of the IC.Type: GrantFiled: April 15, 2022Date of Patent: March 17, 2026Assignee: ANSYS, INC.Inventors: Jimin Wen, Hsiming Pan, Norman Chang, Haiyang He, Mehdi Abarham, Akhilesh Kumar, David Geb, Saeed Asgari, Zhigang Feng, Wenbo Xia, Viralkumar Girishchandra Gandhi

Publication number: 20250173487Abstract: Systems and methods use a neural network based predictor, that has been trained to determine a temperature rise across an entire IC. The training of the predictor can include generating a representation of two or more templates identifying different portions of an integrated circuit (IC), each template associated with location parameters to position the template in the IC; performing thermal simulations for each respective template of the IC, each thermal simulation determining an output based on a power pattern of tiles of the respective template, the output indicating a change in temperature of a center tile of the respective template relative to a base temperature of the integrated circuit; and training a neural network. The trained predictor can be used to determine a temperature rise and then can be appended to a system level thermal profile of the IC to generate a detailed thermal profile of the IC.Type: ApplicationFiled: January 29, 2025Publication date: May 29, 2025Inventors: Norman CHANG, Hsiming PAN, Jimin WEN, Deqi ZHU, Wenbo XIA, Akhilesh KUMAR, Wen-Tze CHUANG, En-Cih YANG, Karthik SRINIVASAN, Ying-Shiun LI

Patent number: 10970437Abstract: Data is received that characterizes a chip in the package system (CPS) having a plurality of wires and vias. Thereafter, using the received data, a chip power calculation is performed. The chip power calculated is used to generate a thermal-aware power map. Further, package and system level thermal analysis is performed using the power map to generate a tile-based CPS thermal profile. A plurality of chip finite element sub-models are then generated that each correspond to a different tile. A thermal field solution is solved for each sub-model so that, for each wire, wire temperature rises are extracted from the corresponding the chip sub-model analysis and combined with temperature values from the CPS thermal profile. This extracting and combining is then used to generate a back-annotation file covering each metal wire and via in the CPS.Type: GrantFiled: January 23, 2020Date of Patent: April 6, 2021Assignee: ANSYS, IncInventors: Hsiming Pan, Zhigang Feng, Norman Chang
