Hello,

I wrote a .va model for a switch with a "if then else" approach using $discontinuity(0) and transition(..) commands to improve management of the sharp transition.
For a transient analysis it is functional, but for a DC-sweep analysis ( to plot an I vs V curve), it fails.

Any idea to help me

           if (state==0) G=Gmax;
           else if (state==1) G=Gmin;            
           G = transition(G_digital,0,1p);
           I(b1) <+ G*V(b1);

Hello,

Finally I succeed by defining a dedicated bloc for DC analysis "analysis('dc')", with the sharp transition transformed in a linear approach.
