Ansoft offers student versions of three of their electromagnetic modeling codes that can be downloaded free of charge:
Ansoft Designer SV provides students and early-career professionals with an easy-to-use tool for applying basic circuit theories and techniques while developing their high-frequency engineering skills.
As a functional subset of Ansoft Designer, the commercially distributed design-management environment and circuit simulator for radio frequency (RF) and microwave hardware development, Ansoft Designer SV exposes engineers to the same design environment widely used in the high-performance electronic design industry.
Ansoft Designer SV contains a complete high-frequency linear circuit simulator, schematic and layout design entry, planar electromagnetic solver, design utilities, and post-processing, all integrated in a common environment. Users are able to create and simulate hierarchical circuit designs for RF and microwave applications, such as filters, small-signal amplifiers, matching networks, power splitters and combiners, couplers, and more. All Ansoft Designer SV projects are upward compatible to work with the commercial version of Ansoft Designer.
Successful high-frequency electronic design is tightly related to physical design and component parasitic behavior. With the addition of a subset of the planar EM capability available in the commercial version of Ansoft Designer, this student version provides a sample of Ansoft's industry-leading electromagnetic solver technology. The planar EM solver lets users generate S-, Y-, and Z-parameters for 2D structures with unlimited stack-up layers (Ansoft Designer SV restricted to under 300 triangles/unknowns).
Ansoft Designer SV allows the simulation of S-, Y-, and Z-parameters, group delay, noise figure, and stability circles of RF and microwave circuits. Utilities include real-time tuning, filter and TRL synthesis, and Smith Tool matching. Post-processing includes rectangular plots, Smith Charts, polar plots, and data tables. Additionally, Ansoft Designer SV comes with a set of real-world examples.
Ansoft offers the Maxwell SV to help engineering students visualize electromagnetic fields and broaden their understanding of electromagnetic physics. The Maxwell SV is a subset of Ansoft's commercially distributed Maxwell 2D. Students can perform AC/DC electromagnetic and electrostatic-field simulation without limitation.
This freely distributed software is intended for electrical engineering students studying topics relating to the design of electromagnetic components, such as sensors, actuators, motors, and transformers.
Simplorer v7 SV is a full-featured version of Ansoft's commercially distributed Simplorer with a limit only on the size of problems that can be solved. Simplorer is sophisticated multi-technology system simulation software widely used by automotive, aerospace, and power electronics systems designers. Simplorer SV is ideal for engineering students studying topics in power electronics, drive technology, electromagnetic actuators and electric machine design, controls, transportation technology, micro machining, mechatronics, and sensor systems. Ansoft offers Simplorer SV to foster and encourage the development of engineering skills throughout the multi-technology systems design community.
Simplorer SV supports the IEEE industry standard VHDL-AMS, a powerful multi-domain, analog, digital, and mixed-signal modeling language for the design of various complex technical systems. Simplorer SV also includes examples specifically designed for topics commonly studied at the junior, senior, and graduate levels.PExprt™ SV provides students and early-career professionals with an easy-to-use tool for magnetic component design and modeling. PExprt SV allows students to learn important design techniques and skills that are relevant to the power electronics industry.
PExprt SV is a limited version of PExprt, the commercially distributed software for the design and modeling of magnetic components such as inductors, planar transformers and integrated magnetics used in power-electronics applications.
