PowerEsim is an
electronic circuit simulation Electronic circuit simulation uses mathematical models to replicate the behavior of an actual electronic device or circuit.
Simulation software allows for modeling of circuit operation and is an invaluable analysis tool. Due to its highly accurat ...
software
Software is a set of computer programs and associated software documentation, documentation and data (computing), data. This is in contrast to Computer hardware, hardware, from which the system is built and which actually performs the work.

A spice is a seed, fruit, root, bark, or other plant substance primarily used for flavoring or coloring food. Spices are distinguished from herbs, which are the leaves, flowers, or stems of plants used for flavoring or as a garnish. Spices a ...
simulator. This knowledge-oriented design approach tool requires a user to possess knowledge about it and about the module being simulated. Within a different kind of simulation,
transformer
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer' ...
design and simulation requires considerable knowledge of the physical concepts, although a transformer is just wires around a magnetic core.
To evaluate the feasibility of a user simulating a circuit without domain knowledge, PowerEsim was developed as a result-oriented approach simulation tool

PowerEsim also handles differential equations by using closed-form equations instead of
numerical methods
Numerical analysis is the study of algorithms that use numerical approximation (as opposed to symbolic manipulations) for the problems of mathematical analysis (as distinguished from discrete mathematics). It is the study of numerical methods th ...
. Some approximations have been made to speed up calculation, leading to a steady-state simulation in PowerEsim claimed to take less than 0.1 second, 1,000 times faster than SPICE simulation. PowerEsim model components are available in the market.
