Xyce is an open source, SPICE-compatible, high-performance analog
circuit simulator, capable of solving extremely large circuit problems
by supporting large-scale parallel computing platforms. It also supports
serial execution on all common desktop platforms, and small-scale parallel
runs on Unix-like systems. In addition to analog electronic simulation,
Xyce has also been used to investigate more general network systems,
such as neural networks and power grids.

The Xyce Parallel Electronic Simulator is a SPICE-compatible circuit
simulator, developed internally at Sandia National Laboratories and funded
by the National Nuclear Security Administration's Advanced Simulation and
Computing (ASC) Campaign. In continuous development since 1999, Xyce is
designed to run on large-scale parallel computing platforms, though it
also executes efficiently on a variety of architectures, including single
processor workstations. As a mature platform for large-scale parallel
circuit simulation, Xyce supports standard capabilities available from
commercial simulators, in addition to a variety of devices and models
specific to Sandia's needs.

The package is intalled at: /opt/Xyce
Remember to set the library and path:

PATH=$PATH:/opt/Xyce/bin

For 32-bit:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/Xyce/lib

For 64-bit:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/Xyce/lib64

To run the suite test:
# cd /opt/Xyce/Xyce_Regression-6.3/TestScripts
# ./run_xyce_regression

For parallel simulation trilinos must be compiled with MPI.

Additonal requirements:
 - MPI (openmpi/mpich)
 - parMETIS
