Hao, we use Sigrity's Broad Band Spice to convert Touchstone Files (TSF) with up to 100 ports into Spice files. With a special 3D FDTD Solver the TSFs are generated and special techniques allow to concentrate with small Spice files on the critical transmission lines of - in our case 94 port - Chip Package, running at 77GHz.
