    Regd. Transient Analysis : save and restore Reply

    Hi

      Its regarding the transient analysis that I am struck with and the issue is as follows :

      I am trying to simulate a 60+GHz oscillator, its simulating fine but there is a phase shift of oscillations for each successive simulation, though I am forcing initial conditions on few nodes. I would like to know if its possible to store all nodes voltages at certain point wrt time, when it is perfectly oscillating, and use these voltages as initial condition - all nodes being set with initial conditions - I would like to do transient analysis.

    Or is there any other way to overcome this ?

    Appreciate your help.

    Regards
    RSR Krishna

    You can use the writefinal option on the tran analysis and then use readic to read the same file. However, it's not perfect - it would be better to use the savefile and recover options (these are on the transient options form) - you can choose which times to write out the saved state (see "spectre -h tran" for more details).

    Regards,

    Andrew.
