Publication number: 20240160820Abstract: Systems and methods are described herein for attribute-point-based timing formal verification of application specific integrated circuit (ASIC) and system on chip (SoC) designs. A target circuit design having a first set of netlists and timing constraints is received. A plurality of key clock-pin-net-load-setting attributes are extracted from the first ported netlists and timing constraints. The clock-pin-net-load-setting attribute mismatch in the result report is checked between the target circuit design and a golden circuit design by comparing the plurality of target attributes with a plurality of golden attributes of the golden circuit design after the target design database is loaded for static timing analysis (STA).Type: ApplicationFiled: January 22, 2024Publication date: May 16, 2024Inventors: Chao-Chun Lo, Boh-Yi Huang, Chih-yuan Stephen Yu

Patent number: 7009836Abstract: A locking device is described. The locking device is utilized to lock and unlock a removable device and especially to be suitable for locking and unlocking the removable device of a notebook computer. The locking device has a latch, an elastic member and a sliding switch. The latch engages a fixing indention of the removable device to fix the removable device. The elastic member provides a force to push the latch forward and a recess for retracting the latch backward. The sliding switch utilizes a stud to glidingly couple to a sliding surface of the latch so that the movements of the sliding switch and the latch form a predetermined included angle, preferably of about 90 degrees.Type: GrantFiled: June 24, 2004Date of Patent: March 7, 2006Assignee: Quanta Computer, Inc.Inventor: Chao-Yuan Lo

Patent number: 7009837Abstract: An integrated locking device is described. The integrated locking device is utilized to lock and remove a removable device and is especially suitable in a notebook computer. The locking device has a latch, a first elastic device, a push arm, and a sliding switch. The latch locks a fixing indention of the removable device to fix the removable device. The first elastic device provides a force to push the latch moving forward and a space for the latch moving back. When the removable device is taken out, the sliding switch pushes the push arm first. Then, a slider of the push arm pushes a sliding inclined surface of the latch to withdraw the latch from the fixing indention. Subsequently, the push arm pushes the removable device outward for releasing the removable device. The movements of the sliding switch and the latch form an included angle, preferably about 90 degrees.Type: GrantFiled: June 24, 2004Date of Patent: March 7, 2006Assignee: Quanta Computer, Inc.Inventor: Chao-Yuan Lo

Patent number: 6762928Abstract: An automatic lifting apparatus for a liquid crystal display module of notebook computers is described. The automatic lifting apparatus comprises a latch hook, a latch button, a latch spring, a lifting plate, at least one lifting spring, and a housing. The latch hook fixes on a liquid crystal display module of the notebook computer. The others parts are positioned inside a base of the notebook computer for locking the latch hook. Furthermore, the lifting plate with the lifting spring power pushes the latch hook moving upward until the latch hook reaches about the height of the latch hook. Therefore, the automatic lifting apparatus can open the liquid crystal display module more efficiently and easily.Type: GrantFiled: August 19, 2002Date of Patent: July 13, 2004Assignee: Quanta Computer Inc.Inventor: Chao-Yuan Lo
