TINA/Spice/TINA-TI: where can I download latest TINA?

Part Number: TINA-TI
Other Parts Discussed in Thread: TIDA-00912, AMC1301

Tool/software: TINA-TI or Spice Models

Hello,

       The latest TINA seems to already be TINA-V11, but on TI website , only TINA-V9 is available. Could anyone tell me where can I download v11? I am using windows 10, v9 seems not quite competible with the OS.

Thank you for helping!

Regards,

Li

    Hi Li,

    Currently we do not have a plan to move away from V9. It provides all the functionalities our customers need and has been very robust.

    Would you mind letting us know what kind of incompatibility issues you are facing?

    Thanks,
    JC

    Hi JC,

         I did have a problem on my simulation with TINA. This is the circuit I am trying to simulate, it is the same as described in TIDA-00912 ( only difference is I am trying to use a unipolar power supply for U1,U2).  If I only have circuit 1, it works well. But if I add circuit 2 in the schematic window, even without connecting to circuit 1, the simulation results of circuit 1 get ruined.  Could you help me solve the problem? Besides, is there an easy way to zoom in and zoom out the schematic ( like normally with ctrl+middle button of mouse)? Thank you for your help!

    Li,
    Would you please attach your .TSC file to this thread?

    Hi John,

         Attached is the simulation file. I am trying to duplicate TIDA-00912, but just found some issues as I described in the post. Thank you for your help

    Thank you Li.
    I don't see any grounds in your circuit. All the Spice simulators I know of need to have at least one ground connection.
    Please try adding a ground in your circuit that makes the most sense to your application.
    Please let me know if you have any more questions.
    Regards,
    John

    Hi John,

        I have GND1 and GND2 in my schematic, as shown in 1 & 2 . But one gnd I was missing is to connect GND1 to the shunt resistor, as shown in 3. I was deliberately doing this , because I was trying to use unipolar power supply for the circuit. U1, U2,U3. Without 3, the circuit actually works well. I want to ask , if disconnecting 3 is a right and good way to design the circuit. Thank you!

    Li,
    From a simulation perspective, if you don't have at least one ground (ground symbol - node 0) on your schematic, then the simulator may not give reliable results.

    I'm not sure about the design since I am not a product expert.

    There have been a number of questions about the AMC1301 in the Precision Data Converters E2E forum.
    I will move the thread to that forum. The product experts there should be able to help you.

    Please let me know if you have any more questions.

    Regards,
    John
