help about the initial condition setting with SpectreS.

Hi everybody,
I have some problems about the initial condition setting with SpectreS.
What I have is a sram array with 1024 cells. I would like to initialize
each cell with either 1 or 0.

With SpectreS, the only way I know is to use the convergency option and
then click the node. Is there any other way which is more efficient? Do
I really need to setup 1024 cells one by one with SpectreS? It is
really painful.

Another problem is also about the initial condition. Is there any way I
can reload the currents and voltage from the last run to the current
simulation. Let the simulation start from the point it ends last time.
Thank you very much for your help!

John

One thing you could do (if it's a transient you're running) is to hit the
"Options" form at the bottom of the choose analysis form (with transient
selected as the analysis), and specify the path to a file in the "readic"
slot.

The file format is just the same as a nodeset or checkpoint file from spectre
- lines containing node name followed by voltage.

Regards,

Andrew.
