Publication number: 20240078370Abstract: Various techniques are disclosed for automatically generating sub-cells for a non-final layout of an analog integrated circuit. Device specifications and partition information for the analog integrated circuit is received. Based on the device specifications and the partition information, first cut locations for a first set of cuts to be made along a first direction of a non-final layout of the analog integrated circuit and second cut locations for a second set of cuts to be made along a second direction in the non-final layout are determined. The first set of cuts are made in the non-final layout at the cut locations to produce a temporary layout. The second set of cuts are made in the temporary layout at the cut locations to produce a plurality of sub-cells.Type: ApplicationFiled: August 10, 2023Publication date: March 7, 2024Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chih-Chiang Chang, Wen-Shen Chou, Yung-Chow Peng, Yung-Hsu Chuang, Yu-Tao Yang, Bindu Madhavi Kasina

Patent number: 11520730Abstract: Disclosed is a data transfer system capable of accelerating data transmission between two chips. The data transfer system includes: a master system-on-a-chip (SoC) including a master transmission circular buffer and a master reception circular buffer; and a slave SoC including a slave reception circular buffer and a slave transmission circular buffer. The slave/master reception circular buffer is a duplicate of the master/slave transmission circular buffer; accordingly, the write pointers of the two corresponding buffers are substantially synchronous and the read pointers of the two corresponding buffers are substantially synchronous as well. In light of the above, the read and write operations of the master/slave transmission circular buffer can be treated as the read and write operations of the slave/master reception circular buffer; therefore some conventional data reproducing procedure(s) for the data transmission can be omitted and the data transmission is accelerated.Type: GrantFiled: March 31, 2021Date of Patent: December 6, 2022Assignee: REALTEK SEMICONDUCTOR CORPORATIONInventors: Po-Lin Wei, Pi-Ming Lee, Chih-Chiang Yang

Publication number: 20200337835Abstract: A medical implant has a center axis and includes first and second flexible waved strands disposed around the center axis. The second flexible waved strand is in spatial communication with the first flexible waved strand to form a plurality of first unit shapes and a plurality of second unit shapes. Therein, the first unit shapes and the second unit shapes are staggered around the center axis. The first unit shapes are coupled to the second unit shapes to cause the first and second flexible waved strands to move substantially along the center axis. The first and second flexible waved strands together define a self-anchoring configuration in a radial direction perpendicular to the center axis so that a ratio of a von Mises stress to an axial displacement of the medical implant during an implant compression of the medical implant is greater than 0.1 and less than 30.Type: ApplicationFiled: April 29, 2020Publication date: October 29, 2020Inventors: Sheng-Chung Cheng, Han-Tang Liu, Chung-Chih Cheng, Jou-Wen Chen, Yong-Guei Chen, Chih-Chiang Yang, Wei-Ting Huang, Yao-Chung Yu, Ting-Shu Lin
