Hi!
I'm = attempting to simulate an oscillator = circuit

Often a = subtle business.

= and I need specified some initial conditions for = simulation. Concretely I want to specifie an initial voltage in a = capacitor.  I use the SPICE-directive block in = gschem

Which netlist = back end?
Which version of SPICE?
Can you show us = your SPICE netlist?

=  and for simulation I check the option "Use ICs" in = GspiceUI,

Can = you tell what GspiceUI is actually telling SPICE?  I don't use = GspiceUI: to me it's just added complexity for no added = functionality.

= however in the simulation results the capacitor voltage does not begin = in the specified voltage value (4.5V).  I have spent a lot of time = solving this problem with not result.
