    LTspice, Warning node is floating

    Hello Arouse1973 and eetech00, Thanks a lot for your answers, so yes eetech00 you are right, the attribute should be D and not X when using "model" statements in the standard.dio. So I tried to simulate with the 12V voltage source and I stil get an error "Time step too small" and the warnings...

    LTspice, Warning node is floating

    Good morning Adam, and thanks a lot. But I still have questions, This 12V was supposed to be generated by the secondary. The Viper16 has an internal start-up using the drain current and when the output 12V is up and running, the Viper16 should switch to this "secondary supply". So my question...

    LTspice, Warning node is floating

    Yes, the encrypted file, I was hoping that we could have solved this without this document. I really don't think they will give it to me and even if they agree to send it to me, I don't think that I would be allowed to post it on the web... No way we could solve this without the encrypted file ?

    LTspice, Warning node is floating

    Ok thanks for the prefix, I will change them, and yes the V104 has no value, I am still waiting for a model from ST Micro. I can't find it on the web (STTH108).

    LTspice, Warning node is floating

    One more question, do I need to put all the attribute prefix to X for all the diode models that I added ?

    LTspice, Warning node is floating

    Hello Harald, So I checked your post, and I don't think I have any of these errors. I do have 3 GND but I don't think it is an error, they need to be connected.

    LTspice, Warning node is floating

    First I would like to say thank you to all of you, I never thought that so many people would want to help me and so quickly. So now to answer to all of your questions. Eetech00 : The value of the attribute prefixe for the MOSFET is already X. And yes I think the main problem comes from the...

    LTspice, Warning node is floating

    Hello, As my first question was answered so quickly, I can't resist to put another one. Still trying to simulate a Flyback converter with a Viper16L from ST, when I'm running the simulation multiple warning appear in the log file, "Warning node Viper16L (D100) is floating" except that all the...

    LTspice, Could not open library file

    Hello, I am trying to simulate a Flyback converter using a Viper16L from ST Microelectronics on LTSpice. ST were nice enough to send me the Viper16L model .asy and .mod. I added them LTspiceIV\lib\sym and LTspiceIV\lib\sub respectively. And I added a Spice directive on my schematic to...
