Models & simulators

Analog simulation programs with TINA-TI? software and SPICE, and the PCB thermal calculator

We make it easy to simulate your design and format the results with our free simulation tools, such as TINA-TI and our PCB thermal calculator. You can also use our extensive model libraries, that are supported within TINA-TI, to accelerate your development.? ?


Virtual instruments allow you to select input waveforms and probe circuit nodes voltages and waveforms to quick-start your design. TINA also has extensive post-processing capability that allows you to format results the way you want them.
