circuit on a breadboard to ensure that it works as expected. Aſter this stage, the user may wish to design a PCB layout of the circuit and have some prototype PCBs made. Tis is easily done in TINA by clicking the PCB Design button in the Schematic Editor, where the screen changes to PCB design. Figure 11 shows the PCB layout of our example amplifier. Te
user has the option of configuring all the usual PCB parameters such as track width, track-to-track size, track-to-via size, track type, inserting text, etc. Other options include auto-place the layout, auto-route, set the layer colours, create a Gerber file of the PCB, create a NC drilling file, and more. Te user can also display the complete design in 3D at
different viewing angles, as shown in Figures 12 and 13. Te bill of materials (BOM) is a list of all the components used
in the circuit and is useful for cost analysis. Tis can easily be displayed by clicking File -> Bill of Materials; see Figure 14. Other TINA features permit the schematic design or netlist
to be exported to other manufacturers’ formats – e.g. Altium, OrCAD, etc, as shown in Figure 15. Users can save schematic designs in TINA as Altium Projects from the File, Export menu point. Te Altium PCB project or native OrCAD netlist can be
imported into OrCAD Capture. Similarly, in OrCAD Capture, the user can click File -> Import -> Altium Schematic Translator to launch Altium-Capture translator to import a TINA generated project. Figure 16 shows the netlist of the amplifier circuit designed in this article, in the form of a PSPICE text file:

TINA packages In addition to simulating digital and analogue circuits, TINA can be used to simulate microcontroller-based systems with processors such as 8051, Arduino, PIC18, PIC24, PIC32, STM32, TI Tiva etc. Te author recommends the Student version of TINA to all electrical and electronic engineering students. Te cost of the off-line Student version was only €12/year when preparing this article.
