can I allocate more memory to icfb extraction operation?

[walala]

Dear all,

I am extracting "extract view" from my "layout view"... The 10000 cell
design is not very large, but I wait for hours and hours the extraction
operation seems no ending...

Can anybody tell me how to increase the memory allocated to icfb
"extraction" operation that it might speed my operation?

Thanks a lo,t

If you're doing this with Diva, then that's potentially quite large... (depends
how big the cells are, and if you're doing it flat, and if you're extracting
parasitics as well).

There's no way to control the amount of memory allocated to any executable
because it is all dynamic - the tools ask for memory that they need (up to what
is available from the system, and up to the maximum for a 32 bit executable (or
64 bit if you're using that)).

It may be that you don't have enough physical RAM; the tools may be getting
enough Virtual Memory, but if there's not enough actual RAM on the machine,
it may be thrashing as it swaps VM chunks back and forth to disk. For
a simple way of viewing this, the utility "top" can be used.
