SIwave: Port Radius and Port Impedance Impact on Accuracy

ANSYS

This technical paper provides correlation studies between measured data and multiple field solver technologies, providing multiple references to different types of analyses that include AC frequency domain comparisons for both power integrity and signal integrity. It includes time domain characterization of the results using TDR and noise measurements for both packages and printed circuit boards.

Impedance

Impedance Scanner

ANSYS

One of the most critical design parameters for PCB manufacturers and designers is the impedance of PCB routing. Failure to meet certain impedance design parameters can make the product on the printed circuit board not meet design specifications. This application note will introduce the capabilities for SIwave to automatically, and quickly, scan the entire PCB or package layout and determine the anticipated impedance using the design stackup to define the dielectric materials and layer thickness.

Near End and Far End Crosstalk Scanner

Near End and Far End Crosstalk Scanner

ANSYS

Crosstalk, or coupling, in high speed printed circuit board and packages represent one of main signal integrity design challenges. The cost of failure is very high and requires careful design strategies. This application note will introduce the capabilities for SIwave to automatically, and quickly, scan the entire PCB or package layout and report Near and Far End crosstalk coefficients.
