摘要:
A tristate driver circuit including a first output transistor for furnishing a first output voltage at an output terminal in the on condition, the first transistor being susceptible to disablement or degraded operation from back biasing in the presence of voltages above a particular level at the output terminal in the off condition, a second output transistor for furnishing a second output voltage at the output terminal in the on condition, apparatus for biasing the first and second transistors to allow operation thereof in the presence of enable signals and to disable operation in the absence of enable signals, and apparatus for eliminating back biasing of the first transistor in the absence of enable signals.

Methods, program products, and systems implementing dynamic parsing rules are disclosed. Log data from a variety of log producers can be parsed using parsing rules to generate information about an information system. The parsing rules can include system parsing rules and custom parsing rules. A state machine can be used to detect conflicts between various parsing rules. A central server can distribute the system parsing rules and custom parsing rules to one or more remote servers for distributed processing. In a hierarchical parsing system, a first tier parser can be used to identify types of sources generating the log data. Log data from each type of log source can be sent to a second tier parser that corresponds to the type of log source.

摘要:
Embodiments of the present invention relate to a computer-controlled method for extracting cell parasitic characteristics for netlist back-annotation in a circuit that comprises a row and column array of repeated cells. The method comprises the steps of generating parasitic and connection data for a row and a column of said cells in the arrayed circuit, duplicating the generated parasitic data for an additional row and an additional column in the arrayed circuit; synthesizing connection data for the additional row from a connected cell in that additional row; synthesizing connection data for the additional column from a connected cell in that additional column, and making the generated parasitic data and the synthesized connection data available for subsequent back-annotation of the netlist.
