Initial Condition for Inductor

tester

Dear All,

I am using  Cadence IC5141 and running a simulation which requires the ".IC" setup for inductors. I tried to put some value under the "initial condition" field of the inductor, but the value is going when I doubly confirmed it with the transient analysis. Are there anything that I may miss or the initial condition of the inductor does not work at all? By the way, are there any alternative way to figure this out? Thanks a lot in advance.

  • I'm not sure what you mean by "the value is going". You might want to clarify.

    Whether initial conditions on devices is controlled by the ic parameter for tran analysis, or the force parameter for dc. This defaults to all for tran, and none for dc. It needs to be dev or all for the initial condition to be used.

    By the way, you didn't specify which simulator you're using. What I'm talking about above is for spectre. The fact you're talking about ".IC" suggests to me you might be using a different simulator?

    Regards,

    Andrew.
