    maybe you have some convergence problems sometimes are explained in the log .don't you.
    check your circuits connections carefully and your pss analysis parameters and the tones you've given before.

    I am just a beginner in learning Cadence. Hope that you could kindly help me. The pss simulation keep running without stopping.
