Droid Tesla Pro
DroidTesla is a simple and powerful SPICE engine. SPICE is an acronym for Simulation Program with Integrated Circuit Emphasis and was inspired by the need to accurately model devices used in integrated circuit design.
DroidTesla simulator solves basic resistive circuits using Kirchoff’s Current Law (KCL) in much the same way a student in a circuits class would,the simulator systematically forms a matrix in accordance
with KCL and then proceeds to solve for the unknown quantities using various algebraic
techniques such as Gaussian elimination and sparse matrix techniques.
For non-linear components, such as the diode and BJT ,DroidTesla engine searching for the approximate solution by making an initial guess at an answer and then improving the solution with successive calculations built upon this guess.
This is called an iterative process. DroidTesla simulation uses the Newton-Raphson iterative algorithm to solve circuits with non-linear I/V relationships.
For reactive elements(capacitors and inductors),the DroidTesla uses numeric integration methods to approximate the state of the reactive elements as a function of time. DroidTesla offers the Trapezoidal(I’ll add a GEAR method later) integration methods to approximate the state of the reactive elements.
Although for most circuits, both methods will provide almost identical results,
it is generally regarded that the Gear method is more stable, but trapezoidal method is faster and more accurate.
