SIMetrix SIMetrix is a mixed-mode circuit simulation package designed for professional electronics engineers. SIMetrix comprises a substantially enhanced SPICE simulator, schematic editor and waveform viewer all seamlessly integrated into one program by SIMetrix Technologies Ltd SIMetrix/Spice Simulator Mixed-mode simulator, superior convergence and speed Convergence is often a problem with many simulators especially in power electronics. This is because the wide range of currents, voltages and conductances present in power circuits stretches the precision of the underlying algorithms. Many other products have to be coaxed into completing such designs by requiring the user to experiment with various option settings. This is rarely necessary with SIMetrix and is the result of over 10 years of development on the core algorithms and model equations along with real world experience in simulator use. Extended sweep modes SIMetrix has six sweep modes applicable to DC, AC, Noise and Transfer Function analyses whereas SPICE has just one for each. For example you can sweep a voltage source at a constant frequency in AC analysis with SIMetrix but not other SPICE programs. Real time noise analysis Applies noise in transient analysis. This unique feature makes it possible to analyse noise in oscillators and sampled data systems. Transient snapshots Stores the circuit state at any point during a transient run. Result can be used to initialise an AC analysis. Useful for investigating the stability of circuits in operating conditions that cannot be obtained using a DC analysis. Model support for IC design Includes, BSIM3, BSIM4, MOS9, MOS11, Mextram, EKV and VBIC models, schematic support for L/W editing. HSPICE® model file compatible Includes: support for HSPICE syntax for parameter expressions; .LIB/.ENDL support; process binning; .GLOBAL; LEVEL 49 and 53 BSIM3 model parameters. Fast Monte Carlo analysis SIMetrix has possibly the fastest Monte Carlo analysis of any PC based product. Unlike other simulators, the SIMetrix Monte Carlo feature is built into the simulator core making it possible to use algorithms that avoid unnecessary repetition. Sophisticated tolerance specification As well as high performance SIMetrix also provides sophisticated tolerance specification allowing simple cases to be setup quickly while providing the flexibility needed for large IC designs. SIMetrix also features a facility to create histograms of analysis data using a wide range of goal functions.
