description Xyce Overview
Xyce is a sophisticated parallel circuit simulator created by Sandia National Laboratories. It facilitates detailed modeling of complex electronic systems, primarily within the semiconductor industry. The software’s capabilities are valuable for engineers and researchers needing advanced numerical analysis and simulation of large-scale circuits, often requiring substantial computing power and specialized knowledge.
help Xyce FAQ
What is Xyce used for compared to regular SPICE?
Xyce is a parallel circuit simulator from Sandia National Laboratories designed to run very large simulations across HPC clusters and supercomputers using MPI. Desktop SPICE tools like ngspice are largely serial, so Xyce's niche is circuits with millions of elements that would choke a normal workstation.
Is Xyce free and open source?
Yes, Sandia releases Xyce as open-source software under the GPL. That makes it freely downloadable, though building it with all its parallel device-model dependencies takes some effort compared to installing a desktop simulator.
What platforms does Xyce run on?
It's most at home on Linux clusters, which is where its MPI-based parallelism pays off, but builds also exist for macOS and Windows. Sandia developed it for large-scale engineering simulation work on US national-lab computing systems.
Can Xyce read standard SPICE netlists?
Yes, it accepts conventional SPICE-style netlists, including common MOSFET model cards like the BSIM family, easing migration from other simulators. It also offers extended modeling capabilities, such as support for Verilog-A device models, that ordinary SPICE lacks.
