**EM Solver Run Control Parameters**

EM solver run control parameters control running built-in 2-D and 3-D electromagnetic full-wave field solvers.**Waveform/Eye Diagram Analysis Parameters**

**Default Device Models**

Specify default linear model to the parts which does not have simulation model.**Network Analysis Parameters**

Control the frequency-domain analysis for extracting network parameters such as S, Y, and Z parameters.**SPICE Run Control Parameters**

You can specify HyperSpice’s simulation control parameters which will affect the simulation time, accuracy, and convergence characteristics.
