在PA设计中,做source-pull时,总是会出现
Error detected by hpeesofsim during HB analysis `HB1'.
No convergence.
Error detected by hpeesofsim during HB analysis `HB1'.
Max. number of Newton iterations reached.
Convergence hints:
o Increase max. iterations to 50.
o Select the Robust convergence mode,
o Select the direct solver.
o Set Matrix Re-use to Robust.
o Select the Krylov solver.
o Increase Krylov Restart Length to 150.
This is the maximum value based on available memory.
o Try TAHB (transient assisted HB).
o Try to sweep a parameter.
o Increase MaxStepRatio.
这样的错误,请教大神
