System and method to locate and correct software errors within a protocol stack for wireless devices
Patent number: 8108727Abstract: The present invention provides a method to test a protocol stack operable to be loaded to a wireless terminal. This involves the creation of simulation scripts from prior test case logs associated with a prior test case executed on a physical wireless terminal.

The simulation scripts are then stored within and retrieved from a library. These simulations scripts are loaded within a simulation environment within computer systems such as a personal computer. The simulation scripts are executed on the protocol stack within the simulation environment to produce a set of results. These results are then compared to a reference log, wherein a favorable comparison indicates a satisfactory simulation. Should an unfavorable comparison result, the protocol stack may be revised.Type: GrantFiled: December 24, 2008Date of Patent: January 31, 2012Assignee: Broadcom CorporationInventor: Matthew Cheng -
