摘要： A method for design verification includes running a simulation of a design in a simulation environment, which comprises a stimuli generator for providing inputs to the design during the simulation. Respective measures of quality are computed for at least some of the simulation states in a sequence of states generated by the environment. State data are saved with respect to at least one of the simulation states. The state data include indications both of the respective simulated state and of the respective environment state. Responsively to the respective measures of quality, the saved state data are recalled so as to restart the simulation from the at least one of the simulation states by returning the design to the respective simulated state and returning the simulation environment to the respective environment state.

摘要： A temporal assertion of a computer program may be defined based on a temporal property. A checker may be generated to monitor the temporal assertion and indicate upon a violation thereof. The checker may be operatively coupled to a debugging module operative to execute the computer program in a debugging session. The execution may be paused in response to an indication from the checker of a violation of the temporal assertion, while continuing the debugging session. A user may then review the state of the computer program to assess what caused the assertion to fail and whether such a violation indicates the presence of a bug or not.

摘要： A leak detection system includes a trace gas leak detector having a wireless base unit, and a handheld wireless remote unit to generate an alphanumeric display of leak rate measured by the leak detector, in response to leak detector information received by wireless link from the leak detector. The remote unit may include a wireless transceiver to communicate with the wireless base unit of the leak detector, a display unit and a controller, responsive to the received leak detector information, to generate the display on the display unit. The remote unit may be configured to control the leak detector and may be configured to display a leak detector operating mode.

摘要： Systems and methods that use a solver to find bugs in a target model of a computing system having one or more finite computation paths are provided. The bugs on computation paths of less than a predetermined length are detected by translating the target model to include a state variable AF for one or more states of the target model, wherein AF(S) represents value of the state variable AF at state S; and solving the translated version of the target model that satisfies predetermined constrains.

摘要： A method uses a SAT solver operating to cycle k to find bugs in a model having finite computation paths therein, wherein said bugs are on computation paths of less than length k. Another method includes adding an additional state variable to a model to be checked, where a governing state machine of the additional variable has a “sink” state. The method includes having a translation using the additional variable whenever a state indicates a bad state and performing satisfiability solving with the model and the translation.
