Title: hspice diagnostic for nonconvergent nodes and ele
Post by xwcwc1234 on Feb 1^st, 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
(xt.net0397) test_dout_ -225.452u -107.207u 2.354

(xt.mn38:is) test_dout_ -249.131u -115.244u 2.664
-------------------------------------------------------------------------------------
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.
