Editing SPICE (section)

=== Open-source successors ===
No newer versions of Berkeley SPICE have been released after version 3f5 in 1993.<ref>{{cite web |title=The Spice Page |url=http://bwrcs.eecs.berkeley.edu/Classes/IcBook/SPICE/ |website=University of California at Berkeley. |archive-url=https://web.archive.org/web/20231208045915/http://bwrcs.eecs.berkeley.edu/Classes/IcBook/SPICE/ |archive-date=December 8, 2023 |url-status=dead}}</ref> Since then, the open-source or academic continuations of SPICE include:

* [[SPICE OPUS]]

Not a descendant but compatible:
* [[Quite Universal Circuit Simulator|QUCS]], which uses an independently-developed Qucsator backend but understands SPICE input. The QUCS-S variant supports using a SPICE-derived backend.<ref>[https://ra3xdh.github.io/ QUCS-S software]</ref>
* Xyce, independent but compatible work from Sandia National Laboratories. Parallel (MPI) C++ for high performance and large netlists.<ref>[https://xyce.sandia.gov/ Xyce software, Sandia National Laboratories.]</ref>
