Has anybody ran into this issue doing tranient reponses with gnucap? It seems like bias point calculations work fine, but when I do a transient reponse even at steady state conditions (all voltages DC), when I look at bias voltages (for example the gate of a diode connected mosfet) it seems like the solver is very noisy to those nodes, as in the bias voltages seems the go up and down 3-4mV at random as if there was some noise on the circuit. When I simulate the circuit with ngspice with the exact same netlist and models, the circuit's transient reponse is a lot more stable.
Is there some settings in gnucap to losen up the solver in a way that would help with this issue?
