Patent number: 7047508Abstract: A method for performing multi-clock static timing analysis to determine whether a timing violation occurs on a logic circuit. A set of clock signals that are expected to cause a logic circuit to be in a worst-case situation if analyzed by using static timing analysis can be selected from a number of possible clock signals by using a simple determination process. The selected set of clock signals are then employed in static timing analysis on the logic circuit to verify whether no timing violation occurs on each signal transmission path of the logic circuit. If not, it indicates that the logic circuit using any selection of the possible clock signals will not cause timing violation thereon. Thus, the static timing analysis can be accomplished efficiently.Type: GrantFiled: February 25, 2003Date of Patent: May 16, 2006Assignee: Via Technologies Inc.Inventor: You-Ming Chiu

Patent number: 6711627Abstract: A method for scheduling execution sequence of read and write operations is disclosed, which is used for controlling the read and write operations between a first device and a second device. First, if there are more than two write operations waiting to be executed, the write operations are executed only after the completion of all of the read operations. If there are no more than two write operations waiting to be executed and there are read operations waiting to be executed, all of the read operations are to be executed when the read operation to be executed is associated with a data address different from the data address associated with the write operation next to the read operation. After all of the read operations are executed, the write operations are to be executed.Type: GrantFiled: June 7, 2001Date of Patent: March 23, 2004Assignee: Via Technologies, Inc.Inventor: You-Ming Chiu
