Description
SIMetrix/SIMPLIS Elite Overview
A unique simulator designed for high-speed analysis of linear and mixed chains.
SIMetrix/SIMPLIS Elite Features
The SIMPLIS application (an abbreviation for “SIMulation for Piecewise LInear System”) was created for the purpose of fast modeling of power supplies and switching stabilizers, as well as studying key circuits of voltage converters. Like the SPICE program, it functions at the level of radio circuit components, but it performs transient analysis 10-50 times faster. SIMPLIS module achieves such modeling speed by using piecewise linear approximation instead of solving systems of nonlinear equations used in the SPICE program. The application performs the following types of analysis: transient processes, phase-frequency response/amplitude-frequency response with a closed loop of automatic regulation and at the operating point. The last analysis is an accelerated calculation of the steady-state mode of operation of a switching power supply with a constant load and supply. For particularly complex cases in terms of simulation, another analysis mode is provided – Multi-Tone AC, which is similar to the two-frequency method for determining intermodulation distortion. In addition, the program has a function for automatic conversion of SPICE models into SIMPLIS format models.
The second program SIMetrix is a full-fledged simulator of analog-digital circuits. It is based on two popular products – XSPICE and SPIСE. The application has a circuit editor, simulator and graphical post-processor. The Newton-Raphson solution is used as the main iteration method, providing fast calculations of transient processes and DC modes. For particularly “tricky” circuits, there is an algorithm of pseudo-transient analysis with isolation/fixation of non-calculable nodal potentials and an adaptable iteration step. The SIMetrix program supports models of MOS9, BSIM3/4, Mextram, VBIC specification elements and is compatible with HSPICE files. In addition, the application has a Bode probe and an efficiency calculator, and also supports the creation of an arbitrary logical block simulating the operation of a digital device.
The distribution with programs includes a detailed user manual, help files and hundreds of examples of completed work from various areas of circuit engineering.
The programs included in this package were developed thanks to the efforts of two partner companies – SIMetrix Technologies (Great Britain, Berkshire County, Thatcham) and SIMPLIS Technologies (USA, Oregon, Portland).
The considered set of programs for simulating electronic circuits is presented in English; there is no Russian language version for it.
Solutions to known problems
Operating System – 64 bit Versions
The following operating systems are fully supported for SIMetrix and SIMetrix/SIMPLIS 64-bit versions:
Windows® 10 Home, Pro and Enterprise – 64 bit editions
Windows® 8.1, Windows 8.1 Pro, Windows 8.1 Enterprise – 64 bit editions
Windows® 8, Windows 8 Pro, Windows 8 Enterprise – 64 bit editions
Windows® 7 Home Premium/Professional/Enterprise/Ultimate – 64 bit editions
Hardware
SIMetrix and SIMetrix/SIMPLIS will operate correctly if:
The system is running one of supported operating systems listed above, AND
The system meets the minimum hardware requirement for that operating system, AND
The system’s CPU supports the SSE2 instruction set. Any system manufactured after about 2005 is likely to meet this requirement.
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 analyzes 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.
