    How to set different accuracy settings for different time periods in transient simulation. Reply

    Hi,

     

    I have a circuit which takes some 10us for the initial transients to settle and reach a steady state.

    Just wondering if can reduce the simulation accuracy to 'moderate'  during the initial times and later make it 'conservative' after reaching the steady state.


    Is it doable using spectre simulator?

     

    Thanks,

    Vamshi

    Vamshi,

    This can be done easily. Use the "Dynamic Parameter" checkbox on the transient analysis form. Then set the Parameter Name to "errpreset" and  choose Parameter vector. Add time 0 and value moderate and also 10u and value conservative. This will then do exactly what you want.

    Regards,

    Andrew.
