  • Patent number: 10402533
    Abstract: Systems, methods, media, and other such embodiments are described for placement of cells in a multi-level routing tree, where placement of a mid-level parent node between a grandparent node and a set of child nodes is not set. One embodiment involves generating a first routing subregion between a first set of child nodes associated with a first grandparent node and a first connecting route from the first routing subregion to the first grandparent node, which together are set as a first routing region comprising the first routing subregion and the first connecting route. Sampling points are selected along the first routing region, and for each sampling point a set of operating values associated with the sampling point is calculated. A position for the parent node is selected based on the operating values for the sampling points.

  • Patent number: 8046208
    Abstract: A simulation apparatus and method is provided for simulating complex high speed interconnects for which closed forms of the S-parameter are incorporated. Differential transmission lines are represented in a causal manner analytically using the 4-port S-parameter without concerns of passivity and stability. Difficult discontinuities of interconnect such as differential vias are represented in closed form and the present invention allows those interconnects to be characterized by 4-port S-parameter measurements or simulation. A complete method of combining causal transmission line models with discontinuities in cascade is provided.

  • Patent number: 7627028
    Abstract: A method for making measurements using a vector network analyzer, and for multi-port S-parameter and T-parameter conversion includes a generalized T-matrix definition that facilitates the conversion between the S-parameters and the T-parameters for multi-port networks based on the well understood and mathematically simple 2-port relations. One contemplated approach generalizes all multi-port networks into two cases: balanced and unbalanced. Through careful selection of the T-matrix, the contemplated method extends 2-port symmetry to multi-port networks and provides an engineering implementable relationship between the S- and T-parameters for multi-port networks. This symmetry extension allows a practical means to cascade and de-embed such networks.

  • Patent number: 6512377
    Abstract: The present invention relates to a via parasitics testing and extracting method for Gigabit multi-layered PCB boards. The method of the present invention is a unique test and extraction process that utilizes a TDR measurement and processes the output data therefrom externally. The testing aspect involves obtaining a TDR module waveform and obtaining a text file with output data, whereas the extraction aspect involves analysis of the data in the text file. This method can be used directly to ascertain a Gigabit via structure without the limitations that are imposed by the conventional methods discussed above, and has been theoretically proven to be highly accurate and much faster than any of the existing methods. The method of the present invention has the potential to be included as a built-in testing feature in high-speed TDR meters, and may also be used in order to design an optimized via.
