TINA

TINA is an electronic circuit simulator and PCB design tool for analyzing, designing, and real-time testing of analog, digital, HDL, MCU, and mixed electronic circuits and their PCB layouts.

You can also analyze SMPS, RF, communication, and optoelectronic circuits. With the integrated flowchart tool, you can generate and debug MCU code. You can also bring your circuit to life with the optional USB controlled LabXplorer and TINALab II hardware.
