hspice diagnostic for nonconvergent nodes and ele
Feb 01st, 2007, 12:25am
 
    Hi ,
        I have following hspice transient analysis diagnostic message:
       ------------------------------------------------------------------------------
                    hspice diagnostic for nonconvergent nodes and elements

                       node    subcircuit       old       new      error
                       name    definition    voltage   voltage   tolerance
                   (xt.ndrive) test_dout_  -156.049m  -154.950m    5.333

   Anyone knows how to solve this non-convergence problem ? Can I set some options parameters to fix it ?

Fix the circuit, look at those nodes for problems.

If at first you do succeed, STOP, raise your standards, and stop wasting your time.
