hi,

I am recently working on a charging control circuit design where i model the battery as  simple capacitor in series with a resistor.

But when i go for the transient simulation using cadence spectre, I get the errors  as given below:


Initial condition computed for node net0115 is in error by 154.824 mV (6.42422 %).
Decrease `rforce' to reduce error in computed initial conditions.  However, setting rforce too small may result in convergence difficulties or in the matrix becoming singular.

could someone please guide me to solve the error.
Is this a critical error to be resolved or can we just leave it and proceed with the design.

vijith,
as far as I remember, this is a warning. You must decide whether this is critical for your circuit or not.
