Magsoft Announces Release of Portunus 3.1

December 8, 2008

The coupled system simulator comes with an extensive set of component libraries that support complex mixed-system analysis and has the ability to incorporate user-defined components created using C++ programs, nonlinear look-up tables, or direct imports of SPICE or VHDL-AMS models.

BALLSTON SPA, NY /PRNewswire/ -- Magsoft Corp. announces the release of Portunus 3.1. Portunus is system-level simulation software that has been developed in cooperation with Adapted Solutions of Chemnitz, Germany, and Cedrat of Grenoble, France.

Portunus is a coupled system simulator that allows both analog and digital components. System modeling can include combinations of electrical networks, block diagrams, and state machines; all cleanly modeled in cascading sub-sheets.

Portunus comes with a series of analysis types to better fit experimental needs and to ensure an accurate solution of transient phenomena at the fastest possible computation times. Portunus simulations now utilize a variable time-step size.

Portunus comes with an extensive set of component libraries to meet the requirements of complex mixed-system analysis. These libraries include:

Passive components

  • Linear and nonlinear resistors, capacitors, and inductors
  • Lamps, switches, relays, and fuses

Semiconductor components

  • Diodes, zener diodes, and thyristors
  • Operational amplifiers
  • BJTs, MOSFETs, and MESFETs

Block components

  • Integrators and derivatives
  • Sample and holds, sums, multipliers, and dividers
  • Limiters and comparators

Voltage and current sources

  • Sine wave, square wave, triangle wave, and PWM

Power Electronics

  • AC/DC, AC/AC, DC/DC, and DC/AC conversion
  • Transformations
  • Sine wave sources, with variable amplitude and frequency
  • Amplitude and frequency Controls

Mechanics and electric machines

  • Rotational and translational mechanics
  • Transformers
  • DC, induction, and PM synchronous machines


  • Conduction, convection, radiation
  • Heat sources and sinks
  • Coupled thermal-electrical models

Portunus now has the flexibility to incorporate user-defined components into the system. These components can be created using C++ programs, nonlinear look-up tables, or direct imports of SPICE or VHDL-AMS models.

According to Shep Salon, President of Magsoft Corp., "Portunus will go a long way toward filling the need for versatile system simulation. Whether an analyst is modeling a simple electrical network, the electromechanical response of a single electric machine, or the full system response of a hybrid vehicle, Portunus will allow them to quickly and easily set up and solve their system and give them the vital responses they need to assess their ideas."
