Changing Transient Simulation step size during the simulation

AmirMasnadi
AmirMasnadi over 1 year ago

In virtuoso ADE transient simulation, I know we can change parameter values during a transient simulation at a given time using Dynamic Parameter feature. Is there any way to change the simulation step size during the simulation ?  For example lets say I am simulating a PLL for 3us and for the first 2us I want low accuracy time step size (e.g. liberal sim) and for the last 1us of simulation I want to have a very high accuracy step size (e.g. moderate or conservative) , is there any way to change the step size at a given time frame ?

    Yes, you can do this by changing errpreset or steppreset (if using SpectreX) through dynamic parameter. The article below explains this, let me know if you are unable to view it:
