[SOLVED] ICC count DECAP cells

[WTing]

Hi
How can I know how many decap cell inside current chip? (in tcl command)

If I were you I'd try to get a flat SPICE netlist (if the design
is in schematic form), grep the cellName (presuming it's one
master used widely) to a file and

wc -l

But that's not the specific method you seem to want.

Depending on CAD platform you might find hierarchy
browsers for layout or schematic which can filter and
count instances-of-master.

You might be able to get similar counting out of a layout
by getting the flat, "extracted" view netlisted in text form.

Thanks
I know count it in gate-level netlist can work.
I still want to know how to get it in ICC GUI or tcl.

sizeof_collection [get_cells -filter "ref_name=~*DCAP*"]

It does not work.
"Warning: No cell objects matched '*' (SEL-004)"

It does not work.
"Warning: No cell objects matched '*' (SEL-004)"

replace DCAP by whatever prefix you have in the dcap cells of your library. this is a simple text matching rule.

icc_shell> sizeof_collection [get_cells -filter "ref_name=~BUF2"]
45
icc_shell> sizeof_collection [get_cells -filter "ref_name=~FILL4"]
Warning: No cell objects matched '*' (SEL-004)
0
DECAP4 fail too.

get_cells -all -filter ...

Yes
It works
Thanks a lot.
