Fritzing is Product Design or EDA in Simplicity

“Fritzing is an EDA – Electronic Design Automation software with a low entry barrier, suited for the needs of designers and artists. It uses the metaphor of the breadboard..”

Fritzing is Product Design or EDA in Simplicity

“in the spirit of Processing and Arduino, developing a tool that allows users to document their Arduino and other electronic-based prototypes, and to create a PCB layout for manufacturing.”

PowerEsim – Online power supply design

The most important characteristic powerEsim is that it provide a virtual laboratory environment for engineer to verify and fine tune their design. Experience engineer use it to optimize their design by saving a lot of time than in real bench.

The circuit simulator is a combination of iteration, equation based apporoach and time step integration. The circuit is defined by non-linear equations and the simulator will first solving the switching condition solution for t=infinity by bracketed iteration, then fine step of point by point results will be generated by those equations for V, I and loss analysis.
