When I a dc analysis for a boost dc-dc converter in Hspice
change the power supply from 2.7v to 4.0v
.dc vdda 2.7 4.0 0.01 /do the dc analysis
I did not use the .ic to set the initaial conditions
but it was aborted.Because it could not converge in the 2.7v
" **error** no convergence in dc sweep curves at 2.7000 "
but when I use .load loading operating point , it still could converge.
.load "E:\xxx.ic0" /loading the operating points
It seems that the ".load " do affect the simulation
Is the using of ".load" right?
And what I want to ask is how to set the initial condition for the dc-dc converter when do the dc analysis in the Hspice?
Are there any other methods to solve the convergence problems?
If someone have successfuly done the dc analysis for dc-dc converter, please help me!
Thanks!
