Catena SIMetrix Simplis 5.4

SIMPLIS is a computer software package specifically designed for the simulation and
analysis of switching power supplies. In a typical switching power system, the
transistors and the diodes function as switches, allowing the system to be characterized
by a cyclical sequence of linear circuit topologies. By taking advantage of the
repetitive piecewise-linear structure of such systems, SIMPLIS is able to perform the
simulation in an efficient and accurate manner.
In order to avoid potential problems caused by simple syntax errors, SIMPLIS
automatically checks the syntax of the input file provided by the user. If syntax errors
are detected in the input file, error messages are recorded in a file for the user to
inspect and correct the errors. This feature allows the user to detect and correct errors
quickly and efficiently.
SIMPLIS-TX is a two-pass time-domain simulator. In the first pass of a simulation run,
only the data pertaining to the state of the simulation at the switching instances are
saved. In the second pass, called the Post-Simulation Processing run, detailed
waveform information is reconstructed from the data generated in the first pass. At the
user-interface level, these two separate operations are not distinguishable since they
are executed automatically by SIMPLIS. Thus SIMPLIS appears as a one-pass
simulator to the user. This internal two-step simulation technique optimizes the
simulation speed and versatility of SIMPLIS.
SIMPLIS-POP (Periodic Operating Point) is an analysis tool that accelerates the
convergence to the steady-state solution of switch-mode power systems. By taking into
consideration the variation of the timing of the intracycle intervals of a switch-mode
system with respect to changes in the state vector, the POP analysis tool accurately
calculates the steady-state solution.
SIMPLIS-FX is a special small-signal frequency-domain analyzer developed for the
analysis of switching power supplies. By calculating the circuit\’s response, over a
range of frequencies, to a small perturbation in the time domain and then using fast
fourier analysis techniques, the necessity of developing state-space averaged
equivalent circuits is avoided. SIMPLIS-FX accurately computes the frequency
response from the same schematic used for time-domain simulation.
