Patent number: 11972188Abstract: To ensure proper operation (e.g., speed and/or function) of standard cells fabricated within an integrated circuit a minimum potential difference between the high and low power supply rails needs to be maintained. IR drop refers to a reduction in the potential difference between the power supply rails and is caused when the switching activity of cells that share a power supply rail is greater than can be provided at a particular time. Before fabrication, placement of the cells is reorganized within bounding box regions. Power density across the power rails within each bounding box is normalized based on spatial and temporal power density characteristics of each cell. The reorganization is IR aware and has minimal impact on timing and IR drop is mitigated because distributing current consumption between the supply rails reduces current spikes and IR drops.Type: GrantFiled: October 19, 2021Date of Patent: April 30, 2024Assignee: NVIDIA CorporationInventors: Shaurakar Das, Haoxing Ren, Santosh Santosh, SeshasaiJyothi Kolli, Muhammad Arif Mirza, Sreedhar Pratty

Patent number: 11970075Abstract: Techniques are presented for scheduling the charging of electric vehicles (EVs) that protect the resources of local low voltage distribution networks. From utilities, data on local low voltage distribution networks, such as the rating of a distribution transformer through which a group of EVs are supplied, is provided to a load manager application. Telematics information on vehicle usage is provided from the EVs, such as by way of the original equipment manufacturer. From these data, the load manager application determines schedules for charging the group of EVs through a shared low voltage distribution network so that the capabilities of the local low voltage distribution network are not exceeded while meeting the needs of the EV user. Charging schedules are then transmitted to the on-board control systems of the EVs for implementation.Type: GrantFiled: March 14, 2023Date of Patent: April 30, 2024Assignee: Weave Grid, Inc.Inventors: Apoorv Bhargava, John Marshall Taggart

Patent number: 11960811Abstract: New techniques for the partitioning of big element blocks in a circuit are disclosed. The techniques partition both pre-layout and post-layout circuits. If a post-layout circuit has different simulation results from a pre-layout circuit, the techniques determine where and how “cross-talk” of the RC networks due to RC extraction is changing the circuit physics behavior from the original design of the circuit. A flow of the local circuit simulation of the pre-layout netlist and the post-layout netlist of the same design is presented. A flow of reference or relative or differential circuit simulation of a known design and a new design of the same kind is described. This Abstract is not intended to limit the scope of the claims.Type: GrantFiled: April 15, 2022Date of Patent: April 16, 2024Assignee: Synopsys, Inc.Inventor: Ningjia Zhu
