Abstract
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.
Claims16
A method for determining timing performance, comprising:
- obtaining clock-to-output times for a processor core;
- using static timing analysis to determine timing data for a memory controller;
- obtaining setup and hold times from the timing data for the memory controller;
- providing a programmatic representation of logic and interconnects for coupling the memory controller and the processor core;
- simulating the programmatic representation of logic and interconnects to obtain delay times;
- inputting the delay times, the setup and hold times and the clock-to-output times to a spreadsheet;
- and
- determining path times from the spreadsheet.
