A welding quality detection system and a welding quality detection method are provided. A detection device applies a force to at least one weld point of a first welded object or a second welded object that are welded together. A displacement detector detects a displacement signal that varies with the force or time between the first welded object and the second welded object based on the force. A detection module receives or records the displacement signal and determines whether a gap exists between the first welded object and the second welded object based on a slope of the displacement signal, so as to detect the welding quality of the weld point quickly and precisely.

Welding quality detection system and welding quality detection method

Method for input/output (IO) design of a chip, including: according to a signal IO pin sequence and associated driving parameters, sequentially placing a signal IO cell in the IO design associated with each of the signal IO pins; after a signal IO cell is placed, performing a simultaneous switching output (SSO) verification step according to physical layout parameters and locations of the signal IO cells placed in the IO design, so as to check whether an SSO specification is violated; if not violated, continuing to place a signal IO cell of a next signal IO pin; if violated, including a decoupling capacitor, an IO power cell and/or an IO ground cell in the IO design.
