Patent 7254794 was granted and assigned to Xilinx on August, 2007 by the United States Patent and Trademark Office.
Method to determine path timing to and from an embedded device is described. More particularly, clock-to-output delays, interconnects and interconnect logic delays, and setup and hold times for input and output paths from a microprocessor core and a memory controller are obtained and determined, as applicable. These times are assembled in a spreadsheet for associating with respective signals. Times for each of the signals are totaled to determine respective path delays for comparison with a target clock period.
