摘要:
A method for use in electronic design models encoded into design software for use in SOI based FET logic design includes simulation of an SOI device and setting a floating body voltage to any desired value at any time during the simulation, by adding to the model an ideal voltage source, whose value is a desired body voltage, in series with an ideal current source, whose value is a constant times the voltage across itself. When the constant is zero no current can flow, and any additional components have no effect on the circuit. When the constant is non-zero, said ideal current source appears to be the same as a resistor such that, current can flow in to or out from the body node, setting its voltage. The constant is kept zero at all times, except when it is desired to change the body voltage. The body voltage can be reset at any time to solve the problem of successive delays in one simulation run and resetting the voltage before each delay measurement starts. To solve the problem of predicting the delay in a delay predictor (for example, NDR rules generation), the offset from the body voltage as a part of the best case/worst case determination is included.

To solve the problem of predicting the delay in a delay predictor (for example, delay rules generation), the offset from the body voltage as a part of the best case/worst case determination is included. The improved process employs a topological analysis for circuit elements to determine whether the element falls in one of several categories, and in the process determines which elements of a circuit might be in AC equilibrium.

A method and apparatus for storing and retrieving information to and from a memory of a hand-held audio database device. The audio database device includes a graphics display provided on a hand-held housing for displaying graphical information. A microphone and a speaker are provided on the housing to receive and broadcast audio information from and to a user, respectively. The audio database device includes a memory configured to store graphical icons and to support a hierarchical memory structure comprising categories, wherein the icons graphically represent the categories. A user-actuated navigation control is provided on the housing and permits a user to navigate the categories in the hierarchical memory structure and to select a desired category. A processor is coupled to the memory, the display, and the navigation control and effects displaying of one of the icons on the display when the user is navigating a corresponding one of the categories, and storing of the audio information in the desired category of the memory.

A voice recognition interface apparatus and method for interacting with a programmable timekeeping device is disclosed. The voice recognition interface includes a display for displaying time, alarm, calendar, and other information, and also includes a microphone and a speaker for facilitating verbal communication between a user and the programmable timekeeping device. A number of illuminatable annunciators are provided on the display for visually communicating prompts to the user. Programming, querying, and other interactive operations are facilitated through use of the voice recognition interface generally by producing a visual prompt to invoke a particular verbal input from the user, receiving the verbal input by use of the microphone, validating the verbal input against a pre-established recognition word library, verbally confirming the verbal input by broadcasting over a speaker pre-synthesized words and phrases retrieved from a message word library, and displaying or otherwise broadcasting information associated with the particular programming, querying, or other interactive operation. The voice recognition interface includes a logic controller that controls and cooperates with a memory, a voice recognition device, a display, and a clock circuit to provide an intuitive voice-driven programming and querying interface for interacting with a programmable timekeeping device. Manually actuatable control switches are also provided for enhancing programming and querying operations. Advanced features include a personal message recording and playback capability, multiple programmable alarms for activating personalized alarm messages, and user-modifiable verbal prompts for personalizing the voice recognition interface dialogue.
