Supported Electromagnetic Solvers

The Electromagnetic Solver assistant supported the following solvers to run extraction and create S-Parameters:

Clarity 3D Solver: Uses a three-dimensional (3D), full-wave, finite element method (FEM) Clarity 3D Solver that uses the industry-leading parallelization technology to ensure that both meshing and frequency sweeping can be partitioned and parallelized across as many computers, computer configurations, and cores as are available.
EMX Planar 3D Solver: Uses a planar 3D solver to simulate high-frequency, RF, and mixed-signal integrated circuits. It allows you to accurately and efficiently simulate large RF circuit blocks, characterize the behavior of passive components, and analyze the parasitics due to interconnect.
It is required to set the paths to the solvers you want to use for electromagnetic simulations in the PATH environment variable or the solver-specific environment variables, EMX_PATH or CLARITY_PATH.

You can also use the CLF-specific executables. The first command line argument for the executables should be a .clf file. The other arguments should be passed to the actual binary.
```
emx_clf file.clf [list of emx command line options]
```
```
gdsview_clf file.clf [list of gdsview command line options]
```
To use the executables, set EMX and GDSview in the $PATH. The executables use the path to a .clf file and invoke EMX/GDSview on it.
