Altos Liberate Char Error: Expecting XX of DC values but read back 0 instead

Hi there,

I am a newbie in Digital IP characterization, here is the scenario,

I have an IP which needs to initiate all the internal nodes to '0' but the problem is i couldn't find a way to do so,
I have then see this three command as below which i think is most related to what i want,

set_var sim_init_condition_estimation_mode 1
set_var sim_use_init_duration 1
set_var sim_init_duration 1e-09

However during the runtime i m getting the error like "Expecting XX of DC values but read back 0 instead".
I aware that the simulation continue after the reporting of the error. i wonder this is a fault alarm due to licensing proble
or real error? Can anyone please advise on this.

Also my apologize to the operator for posting it here since i am not sure should there be the Altos tools discuss in the cadence
forum.

Many thanks in advance.

Regards,
