Data points sample rate

QSPICE
1

Hi there, when I change the simulation time steps in a .tran simulation. Data points interval dindn’t change at all. In the example I am showing I’ve set the timeSteps for 10pS and the interval of the data points in the plot stays 250pS.
I’ve bem searching for some parameters related to datapoints sampling on Qspice menus but I did not find nothing at all.

Best regards

Two options to set Max Time Step (Qspice is not constant time step, but you can set a max time step)

  1. In Help > Simulator > Command Reference > Non-Linear Transient Analysis (.tran), it mentioned two syntax. The traditional Berkeley Syntax can set MAXSTEP. In your example, the format should be
    Syntax: .tran IGNORED TSTOP [TSTART [MAXSTEP]] [UIC]
    .tran 0 4u 0 10p"

  2. In Help > Simulator > Command Reference > Simulator Option (.option), there is an option MAXSTEP to set max step size for .tran and .bode. In your example, the format should be
    .tran 4u
    .options MAXSTEP=10p

Yes you are right! It was that Ignored “0” in the begining that solves. Now the 10pS steps parameter is taking into acount. Thank you
