System requirements

SIMetrix and SIMetrix/SIMPLIS runs on Microsoft® Windows® platforms.

Operating System

The following operating systems are fully supported for full versions of SIMetrix and SIMetrix/SIMPLIS:

  • Windows® 11 Home, Pro (including variants) and Enterprise
  • Windows® 10 Home, Pro and Enterprise - 64 bit editions

Virtual Machines, Emulators and Older Operating Systems

Important: we only offer full support when running SIMetrix on supported operating systems running directly on physical hardware. This excludes running SIMetrix in virtual machines or under emulation on non-supported operating systems. This doesn't mean you can't run SIMetrix on such systems or that we won't support such systems at all. It does mean that we will only be able to help with problems that can be reproduced on a supported OS.

In particular, we cannot help with problems with dongles if SIMetrix is running in a virtual machine or under emulation.

32 bit Operating Systems

The only version of SIMetrix/SIMPLIS available for a 32 bit operating system is version 8.3. This can be obtained from here. All other versions require a 64 bit operating system.

Windows® on ARM

SIMetrix and SIMetrix/SIMPLIS are not supported running on ARM based systems


SIMetrix and SIMetrix/SIMPLIS will operate correctly if all the following conditions are met:

  • The system is running one of supported operating systems listed above
  • For version 9.1 and later, the processor must meet the specification described here
  • The system meets the minimum hardware requirement for that operating system

SIMetrix and SIMetrix/SIMPLIS are CPU-intensive applications and will benefit from the most powerful processors and largest memories.

Multicore support

SIMetrix Pro and SIMetrix/SIMPLIS Pro are able to use up to 4 physical cores, while SIMetrix Elite, and SIMetrix/SIMPLIS Elite can exploit 16 physical cores.

Please, however, be aware of the following:
  • Some processors increase the apparent number of CPUs by using a technology called "Hyperthreading". SIMetrix and SIMetrix/SIMPLIS do not directly use hyperthreaded (also known as "logical") CPUs.
  • The greatest benefit from multiple cores is achieved when running Monte Carlo analyses and other multiple analysis modes. This applies to both SIMetrix and SIMPLIS simulators. For this application, typical performance benefit of about 75% of the core count can be achieved. So for 4 cores a Monte Carlo run may execute about 3 times faster. The SIMetrix simulator can also exploit multiple cores to gain a speedup for single runs, but the performance benefit achieved is much more modest and typically there is little benefit in having more than about 4 cores.

System requirements for older versions

Older versions of SIMetrix will run on the operating systems supported at the time of their release. In general we have found that all 32-bit Windows® versions of SIMetrix back to version 1.0 will also usually run on any later 32-bit Windows® operating system, but often need special install procedures. However, we have not tested every version of SIMetrix with every version of Windows® and can make no guarantees or offer any support for non-supported operating systems.

There can be problems with older versions running on 64-bit systems. In particular versions 5.3 or earlier using portable licenses (i.e. with a USB security key) will not work with any 64-bit system.
