Validation of electrical performance of an electronic package prior to fabrication

An electrical resistance determination method, comprising the steps of:

• specifying as input to a computer readable program code a description of N electrical networks comprised by a first substrate, said description including specification of a plurality of first ports on a first side of the first substrate for each electrical network such that all of said first ports are electrically isolated from one another, said description further including specification of a plurality of second ports on a second side of the first substrate for each electrical network such that all of said second ports are electrically connected to a common voltage said N≧1;
• and
• following said specifying, executing said computer readable program code by a processor of a computer system, said executing including computing for each electrical network of the N electrical networks an unadjusted electrical resistance between each first port and a port of the second ports,
• wherein the electrical resistance is a nearest-neighbor adjusted electrical resistance between each first port and the port of the second ports,
• said nearest-neighbor adjusted electrical resistance being with respect to a second electrical network of the at least one electrical network,
• said nearest neighbor adjusted electrical resistance being determined in accordance with Delaney Triangulation,
• said executing further including displaying a perspective plot of said computed electrical resistances as a bar oriented about normal to each first port on the first side of the substrate,
• each bar having a height that is a monotonically increasing function of the computed electrical resistance at the first port at which the bar is located,
• said monotonically increasing function being a linearly increasing function,
• each bar having a color or shade of gray that is reflective of a range of electrical resistances that encompasses the computed electrical resistance at the first port at which the bar is located,
• said executing further including, in response to a selection of a bar B of the perspective plot, displaying a numerical measure of the computed electrical resistance at the first port that is associated with the bar B.
