    • A link simulation tool for simulating high-speed communications link systems is provided. Communications links may include link subsystems such as transmit (TX) circuitry, receive (TX) circuitry, oscillator circuits that provide reference clock signals to the TX and RX circuitry, and channels that link the TX and RX circuitry. The link simulation tool may model each of the subsystems using behavioral models. The behavioral models may include characteristic functions such as transfer functions, probability density functions, and eye characteristics. The link simulation tool may have a link analysis engine that is capable of performing two-dimensional (two-variable) convolution operations and in applying dual-domain (frequency-time) transformations on the characteristic functions provided by the behavioral models to simulate the performance of the link system. The link simulation tool may have an input screen that allows a user to specify desired link parameters and a data display screen that display simulated results.

    • The present invention is a method and apparatus for creating a reduced-order IC interconnect model, which incorporates variations in interconnect process parameters, and models both on-chip and off-chip interconnects. The method is based on mathematically representing an IC interconnect system, including mathematical interconnect process parameter terms, which are manipulated to facilitate simplification of an IC interconnect model. The IC interconnect model is then simplified by using a mathematical technique called state-space projection. Specifically, an IC interconnect system is represented with at least one modified nodal analysis equation (MNA) that is based on frequency, interconnect process parameters are added and substituted back into the MNA(s), terms with interconnect process parameters are explicitly matched. A state-space projection is created, which implicitly matches frequency terms. The state-space projection is used to create the reduced-order IC interconnect model.

    • The present invention provides a method, a system, an access terminal and an access network for transmitting a forward traffic channel at a fixed rate. In the present invention, an access terminal transmits identification information of one or more specific forward carrier links to an access network when the access terminal determines that it needs to receive one or more forward traffic channels at a fixed rate from the one or more specific forward carrier links as designated. The access network transmits one or more forward traffic channels at the fixed rate according to the received identification information. The inventive access terminal may choose to receive a forward traffic channel(s) at a fixed rate from a forward carrier link(s) of a sector(s) as designated, thereby enhancing flexibility in transmitting a forward traffic channel and improving the multiple carrier EV-DO technology.

    • This specification discloses a method for automatic testing PCMCIA cards. The method first loads in the main library of the control panel, then checks and displays the PCMCIA module using the application interface of the control panel library. A SetwindowsHook then loads in dynamic link library (DLL) and checks the TextOut function address from the ModuleList in PCMCIA module for interception and data storage. The peripheral description values are stored in a list and compared with the data intercepted and stored in the ModuleList to complete a test report on correctness or error.
