| 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. Thie unique feature makes it possible to analyse noise
in oscillators and sampled data systems.
Transient snapshots (NEW for Release 4.5). 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 and MOS9 models, schematic support for L/W editing. VBIC 1.1.5
available as a plugin (currently in BETA). See our Resources page
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
unneccessary repetition.
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.
Multi-step analysis. Repeats an analysis while
varying some circuit variable using one of six modes.
Non-linear magnetics with support for air gaps.
Includes models for 670 standard parts including Ferrites and MPP
cores. Other devices can be entered easily by specifying geometry,
permeability and core material.
Transient restart. Transient analysis can be restarted
after the stop time has been reached. Useful when a circuit takes
longer to settle than originally expected. |
