#317 Ngspice cannot run transient with s2p files in matching networks Issue created by shafinhossain *Environment*\n\nqucs-s 24.3 \nngspice 43\n\n*Expected Behavior*\n\nissue2 \nUsing Ideal Inductors in the matching network of the Power Amplifier (180 GHz) transient simulation and S parameter simulation both are successful.\n\n*Actual Behavior*\n\nissue1 \nUsing openEMS the ideal inductors were replaced by S2P files. But this time the simulator could not run Transient Simulation but does support S parameter simulation. \nNote: Only occurs when the inductors in the matching network are replaced by S2P files, however when the RF Choke or Degenerative Inductor is replaced by S2P files, transient does run.\n\n*Steps to Reproduce the Problem*\n\n1. Create an amplifier circuit with npn13g2, and proper matching networks (L matching)\n2. Replace the inductors in L matching with S2P file.\n3. Run transient simulation and see it fail.
