Capacitors General form: CXXXXXXX N+ N- VALUE Examples: CBYP 13 0 1UF COSC 17 23 10U IC=3V N+ and N- are the positive and negative element nodes, respectively. VALUE is the capacitance in Farads. The (optional) initial condition is the initial (time- zero) value of capacitor voltage (in Volts). Note that the initial conditions (if any) apply 'only' if the UIC option is specified on the .TRAN control line. Bas --
