New Simulation Support (New Feature Summary)

Created: July 11, 2019 | Updated: January 14, 2020
This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer (with Altium Designer Enterprise Subscription) and a connected Altium 365 Workspace. Check out the FAQs page for more information.

This Altium NEXUS software release introduces a new era for its circuit simulation capabilities through the introduction of an advanced new SPICE simulation engine developed by Altium. The replacement engine offers immediate performance benefits and provides a scalable foundation for future development in mixed circuit simulation in Altium NEXUS.

The new simulation engine and its core algorithms offer a performance that is multiple times faster than before, coupled with vastly improved solution convergence, accuracy and reliability.

As a completely revised foundation for future updates to the mixed simulation feature, it also paves the way for a fresh approach to simulation model sources. As part of this development, Altium's proprietary SimCode™ digital models are no longer supported and will be replaced by support for more contemporary model formats.

This release also includes a large number of Simulation bug fixes (see Release Notes).
