  • Patent number: 7260495
    Abstract: A system and method for test generation for system level verification using parallel algorithms are provided. The present invention generates test patterns for system level tests by exploiting the scalability of parallel algorithms while allowing for data set coloring and expected result checking. Based on the characteristics of the system being tested an iterative parallel algorithm is selected from a plurality of possible parallel algorithms. The selected parallel algorithm is then separated into separate program statements for execution by a plurality of processors. A serial version of the selected algorithm is executed to generate a set of expected results. The devised parallel version of the selected algorithm is then run to generate a set of test result data which is compared to the set of expected results. If the two sets of data match, it is determined that the system is operating correctly.

  • Patent number: 7251570
    Abstract: Systems and methods for ensuring data integrity in a mesh network. A mesh network can include multiple RF devices. Transmitting quality data in or on the mesh network is improved using communication validation functions. The communication validation functions ensure a reliable communication network, preserve data during a network outage, and validate data. The communication validation functions can measure or control data quality within a communication and analysis network. The communication validation function operates to control data quality, for example, by measuring the quality of wireless links, ensuring the presence of redundant links, testing the ability of the mesh network to establish a backup communication path, generating alarms based on communication thresholds, tracking the communication path followed by communication packets, and identifying placement locations for additional RF devices.

  • Patent number: 7246018
    Abstract: An interpolator testing system and method comprises an interpolator that includes a phase shift module. The phase shift module receives a reference clock signal and generates M clock signals having phase shifts in increments of 360/M degrees relative to the reference clock signal. A phase select module receives the reference clock signal and a recovered clock signal during a normal mode and generates a select signal based on a comparison of the reference clock signal and the recovered clock signal during the normal mode. A selector receives the M clock signals and outputs one of the M clock signals as the recovered clock signal based on the select signal. A recovered clock counter counts an attribute of the recovered clock signal during a test mode. The phase select module sequentially selects the M clock signals N times during the test mode.
