    Abstract: Embodiments of a computer system, a method, an integrated circuit and a computer-program product (i.e., software) for use with the computer system are described. These devices and techniques may be used to calculate the total time delay in a signal path due to crosstalk from a group of crosstalk aggressors that are associated with a group of signal paths. In order to properly account for statistical behaviors in the switching times and directions of the switching patterns in the group of signal paths, the time-delay contribution from each of these crosstalk aggressors may be modeled as a corresponding statistical random variable. Because the number of crosstalk aggressors are usually much larger than the number of stages in the signal path, the calculated total path delay may be less pessimistic. Furthermore, in order to detect potential timing violations, the time-delay contributions from additional dominant crosstalk aggressors can be modeled using non-statistical worst-case deterministic values.

    Abstract: Embodiments of a computer system, a method, an integrated circuit and a computer-program product (i.e., software) for use with the computer system are described. These devices and techniques may be used to analyze an electrical characteristic of a logic gate electrically coupled to an output network in a stage. In particular, during the analysis, the effective capacitance of an output network coupled to a logic gate is approximated as a function of a total resistance of the output network, a total capacitance of the output network, and a geometric parameter of the output network. For example, the effective capacitance may be approximated as a function of a ratio of the product of the total resistance and the total capacitance to the fanout count of the output network. Using the effective capacitance and other parameters, such as a slew rate of an electrical signal applied to an input of the logic gate, an electrical characteristic of the logic gate, such as an input capacitance, is determined.

    Abstract: The present invention provides a mass spectrometer having an ion lens capable of transporting an ion having a large mass to charge ratio with a high level of ion-passing efficiency even under a low-vacuum atmosphere. In conventional atmospheric pressure ionization mass spectrometers or similar mass spectrometers, applying an excessively high voltage to the ion lens undesirably causes an electric discharge. Therefore, the passing efficiency for an ion having a large mass to charge ratio cannot be adequately improved, which leads to a poor detection sensitivity. To solve this problem, the mass spectrometer according to the present invention includes a voltage controller 21 that controls a variable radiofrequency (RF) voltage generator 24 so that both the amplitude and the frequency of the RF voltage applied to the lens electrodes of an ion lens 5 are changed according to the mass to charge ratio of an ion to be analyzed. This control enables the ion lens 5 to focus an ion and transport it to the subsequent stage with a high level of passing efficiency even in the case of analyzing an ion having a large mass to charge ratio. Thus, the detection sensitivity is improved. The aforementioned control is conducted on the basis of the control data stored in a voltage control data storage 22. These data are obtained in advance by a measurement of a sample containing a substance having a known mass to charge ratio, in which the intensity of the signal of an ion detector is maintained while the analysis conditions are changed.

    Abstract: A system and method for testing a Link Control Card (LCC) of a storage device includes a host, a middle plane (MP), a switch, and a testing device array. The host is connected to the testing device array for sending out command sets and receiving results. The MP is connected between the LCC and the testing device array. The switch determines the LCC to output hard reset signals and the hard reset signals are transferred to the testing device array via the MP.

    Abstract: Under the present invention, as a user/developer is developing a software program using an IDE, the user can designate a remote source container(s) (e.g., located on a server or the like that is remote from the local computer system) for one or more source files. When a remote source file is needed (e.g., during debug of the program), a cache on the local computer system will be examined first. If the remote source file is not present, or if the cache is not up to date, the remote system will be called. When the remote source file is received back on the local computer system, it will be stored in the cache and then made available to the user as needed. The system of the present invention is extensible to provide support for various platforms and to provide look up of source files inside additional archive types.

    Abstract: The present invention generally combines the concepts of view filtering with query filtering to provide an improved object filtration mechanism. Under the present invention, input for an object and a filter string is received. It is then determined whether the filter string was used in a previous query. If not, a query filter is generated based on the filter string if the filter string was not used in a previous query. Thereafter, a query for the object is generated and performed while applying the query filter. When results of the query are received, a view filter (generated based on the filter string) is used to filter the results. After this additional filtering, a view of the results is generated.
