Merging of Nets
Definition: Let i and j be nets for which the following holds:
(a) i and j are not adjacent in the HIG
(b) There is no direct path between i and j in the VCG
Then these nets can be assigned to the same track and hence they can be merged in the VCG
(1) Combine nodes i and j into node i? j in VCG
(2) Update zone representation such that i·j occupies zones of i and j and all zones in between
