A shielding structure is provided for shielding a signal path extending between a first layer and a second layer in an electronic device at a transition region with a transition that extends in a first direction and a second direction orthogonal to the first direction. The shielding structure includes a shielding structure portion, which includes a first shielding via in proximity to a first area of the signal path at the transition; a second shielding via in proximity to a second area of the signal path at the transition; and an area metallization electrically coupled to the first shielding via.

Shielding structures for signal paths in electronic devices

A method of packaging a semiconductor device (10) partitions a distribution substrate (20, 40) into regions (31-34) such that attachment points (22) for electrically coupling to the semiconductor device lie in a first region (31). A first set of conductors are routed from a portion of the attachment points to terminals in a second region (32). Another portion of the attachment points are assigned to available routing channels of the second region for disposing a second set of conductors across the second region to a third region (33). Partitioning improves routing efficiency without requiring objects to be located on grid points or restricting the angles of the routing channels.

Integrated circuit interconnect method and apparatus

A computer implemented method (10) for designing a signal distribution architecture (40). The method includes developing a signal distribution network architecture model (11) and a delay model (12). The delay model (12) describes a temporal relationship of inputs and corresponding outputs of the signal distribution architecture model (40). The signal distribution network architecture (11) and delay (12) models are combined to form a master model (13). A set of values are inserted into the master model (13) to generate a response model (16). The response model (16) is used to select the signal distribution architecture (40).

Method for designing a signal distribution network

An instrumentation system includes a hand-held computer-based measuring meter having a visual display and a plurality of individual sensor modules that can be selectively coupled to the measuring meter for measuring one of a variety of parameters such as temperature, pressure, or the like. Each sensor module includes a sensor responsive to a particular stimulus, as well as a data memory for storing information about the sensor. When the sensor module is interconnected with the measuring meter, the measuring meter accesses the memory of the sensor module to input data corresponding to sensor type, an accuracy code, calibration point data, and a calibration date code. The measuring meter compares the calibration date code to the current date to determine whether the sensor module requires recalibration. The measuring meter uses the accuracy code data to determine the number of significant digits displayed by the visual display. The measuring meter uses the sensor type code and calibration points to calibrate the measuring meter relative to the sensor module and to select the algorithm used to compute the current value measured by the sensor module.
