Reportedly, one of the best features of TINA is that a simulated circuit can easily be implemented on a PCB with auto-placement and auto-routing capabilities. Users can also use the Gerber plotting and CNC drilling options of TINA to learn, design, and implement a prototype of their projects. That's “awesome,” but before any PCB can come into play, you have to master elementary circuit simulation. Here's an up-tempo primer to TINA you cannot afford to miss and do on your PC.
