Cadence® Allegro® is a popular board layout tool but it lacks a 3D-trace-and-via EM simulator like ADS Momentum. Fortunately, you can export your critical nets to Agilent ADS Layout, run Momentum, and extract multi-port S-parameter data from the structure. With S-parameters in hand you can go back into Allegro, or do further optimization, design, and analysis in ADS. The following two videos show you 1) how to export the artwork from Allegro to ADS and 2) how to run Momentum. Momentum uses powerful basis functions called Green’s functions that are precomputed for trace and via current flows. The fields are rapidly solved full 3D.
Design flow integration
If you have an ADS license, the zip file is in the ADS distribution at
C:\ADS2009U1\ial\import_kit\import_allegro_2.5_dk.zip (Assumes ADS is installed in
C:\ADS2009U1\ folder). The doc (including installation instructions) is here (Knowledge Center login required.) Allegro DFI presently works with Cadence Allegro PCB version 15.7 and higher and Allegro Package Designer and Cadence SiP versions 16.01 and higher.
