20160125109 | Polymorphic Circuit Simulation System - A method for operating a data processing system to simulate a circuit that includes a plurality of circuit devices connected by interconnects. A layout description of the circuit is provided in which the devices are connected by interconnects. Each interconnect is associated with a line definition that includes a physical description of an interconnect between two of the circuit devices and a simulation model to be used in simulating the interconnect during simulations of the circuit. The line definitions are user selectable from a list of available line definitions. A circuit netlist is generated by reading physical interconnects from the layout. At least one of the interconnects is replaced by a plurality of transmission line devices, each device being associated with the simulation model included in the line definition. The circuit is then simulated using the netlist. | 05-05-2016 |
20160085223 | Digital Triggering Using Finite State Machines - An apparatus that can be configured for various functions such as a digital oscilloscope, logic analyzer or frequency analyzer is disclosed. The apparatus includes a symbol generator, an FSM, and a controller. The symbol generator generates an ordered sequence of symbols from an analog input signal. The symbols have a number of states that is less than or equal to 16. The controller causes the FSM to search for a pattern in the sequence of symbols that identifies a corresponding pattern in the analog signal. A portion of a digital sequence generated from the analog signal is then displayed based on the location of the pattern in the sequence of symbols. | 03-24-2016 |
20150242533 | Method and Apparatus for Analyzing Data Flows - A method of operating a data processing system to display a plurality of list entries is disclosed. Each list entry includes a timestamp, an identifier, and a message. The method includes sorting the list entries by the identifier associated with the list entries and displaying a data flow chart on a display associated with the data processing system. The data flow chart has a plurality of rows. Each row is a graphical view of the list entries having a given identifier. Each row includes a graphical element representing each message and a row label indicating the identifier associated with that row. Each row has a time region representing a time axis on which the graphical elements are placed, each of the graphical elements being placed at a location in the time region determined by the timestamp associated with that message. | 08-27-2015 |
