Appnote: Merging via arrays in ADS 2012

if you are doing EM analysis of RFIC inductors or other passive on-chip structures, then this appnote might be for you. 

In RFIC, larger vias are created as via arrays. The size of each single via is usually fixed by the technology rules, and via arrays are created where a larger via cross section is needed. This application note describes efficient modelling of via arrays in Agilent ADS with the Momentum EM solver. Two methods are discussed: via merging with an AEL script, and via merging with "derived layers" in ADS 2012.
