  • Patent number: 10372854
    Abstract: A method is presented for responding to user input by displaying when a circuit has a property expressed by an assertion based on data indicating values of signals of the circuit at a succession of times. The assertion expresses the property as a first sequence of expressions, and separately defines for each expression a corresponding evaluation time relative to the succession of times at which the expression is to be evaluated. The circuit has the property only if every expression of the first sequence evaluates true at its corresponding evaluation time. The method includes displaying a representation of each expression of the first sequence and identifying each variable that caused that expression to evaluate false and distinctively marking that variable's symbol relative to other variable symbols within the display for each expression of the first sequence that evaluates false at its corresponding evaluation time.

  • Publication number: 20160060857
    Abstract: A bug-proof and odor-proof drainage device includes a cover, a base, and a connecting pipe connecting plural bases of different bug-proof and odor-proof drainage device. The cover has plural draining holes arranged in intervals. A capping is disposed on the bottom surface of the cover. The base has a through hole surrounded by a wall part extending upward. The base is embedded in floors of bathrooms and kitchens and connected to a draining pipe through the through hole and also connected to different bases by the connecting pipe. Water flows into the base, and then circuitously sinks to flow over the wall part and rises along the wall part, thereby flowing into the draining pipe from the through hole, such that a portion of water is stored within the base for preventing bugs and odor from entering through the draining holes.

  • Patent number: 9158476
    Abstract: An operation mode switching method for a memory storage apparatus, a memory controller and a memory storage apparatus using the method are provided. The operation mode switching method includes receiving at least one access command from a host system and determining whether the access command conforms to a predetermined pattern. If the access command conforms to the predetermined pattern, an operation mode of the memory storage apparatus is switched from a first mode to a second mode. The access command includes a first write command including a write string, and the memory storage apparatus executes an operation corresponding to the write string. Accordingly, the method switches the operation mode of the storage memory apparatus by determining the pattern of the access command, so as to simplify the procedure of switching the operation mode and effectively decrease the probability of switching the operation mode incorrectly.

  • Patent number: 8479132
    Abstract: A computer processes simulation data indicating values of circuit signals as functions of simulation time to determine whether a circuit exhibits a property defined by an assertion. The assertion expresses the property as a sequence of expressions, each a function of one or more variables, where each variable represents a value of one or more signals or a value of another sequence of expressions. The assertion statement separately defines an evaluation time for each expression, a particular simulation time at which the expression is to be evaluated. Each expression must evaluate true if the circuit has the property. The computer produces a display including a representation of each expression of the property including a separate variable symbol for each of its variables. For each expression that evaluated false, the computer identifies each variable that caused that expression to evaluate false and distinctively marks that variable's symbol relative to other variable symbols within the display.
