[SOLVED] How to extract list of all cells in synthesis library?

Hi,

I want to see list of all cells defined in a synthesis library. I am using Design Compiler for synthesis.
Any suggestion?

hi

Can you try check_library or get_lib_cell <libname>/*
What is the idea behind doing this?

A simple grep "cell (" <libname> > filelist

will also help you put all cells in the file

You can try get_cells and get_lib_cells commands. Try referring to DC user manual for more on these.

I think i am confused.. wont get cells revert back with design instance names and not libcells

using get_lib_cells I got the following results. However, it puts ... at the end of the list while remaining cells are not listed.


get_lib_cells saed90nm_max_lt/*
{saed90nm_max_lt/AND2X1 saed90nm_max_lt/AND2X2 saed90nm_max_lt/AND2X4 saed90nm_max_lt/AND3X1 saed90nm_max_lt/AND3X2 saed90nm_max_lt/AND3X4 saed90nm_max_lt/AND4X1 saed90nm_max_lt/AND4X2 saed90nm_max_lt/AND4X4 saed90nm_max_lt/AO21X1 saed90nm_max_lt/AO21X2 saed90nm_max_lt/AO221X1 saed90nm_max_lt/AO221X2 saed90nm_max_lt/AO222X1 saed90nm_max_lt/AO222X2 saed90nm_max_lt/AO22X1 saed90nm_max_lt/AO22X2 saed90nm_max_lt/AOBUFX1 saed90nm_max_lt/AOBUFX2 saed90nm_max_lt/AOBUFX4 saed90nm_max_lt/AODFFARX1 saed90nm_max_lt/AODFFARX2 saed90nm_max_lt/AODFFNARX1 saed90nm_max_lt/AODFFNARX2 saed90nm_max_lt/AOI21X1 saed90nm_max_lt/AOI21X2 saed90nm_max_lt/AOI221X1 saed90nm_max_lt/AOI221X2 saed90nm_max_lt/AOI222X1 saed90nm_max_lt/AOI222X2 saed90nm_max_lt/AOI22X1 saed90nm_max_lt/AOI22X2 saed90nm_max_lt/AOINVX1 saed90nm_max_lt/AOINVX2 saed90nm_max_lt/AOINVX4 saed90nm_max_lt/DEC24X1 saed90nm_max_lt/DEC24X2 saed90nm_max_lt/DELLN1X2 saed90nm_max_lt/DELLN2X2 saed90nm_max_lt/DELLN3X2 saed90nm_max_lt/DFFARX1 saed90nm_max_lt/DFFARX2 saed90nm_max_lt/DFFASRX1 saed90nm_max_lt/DFFASRX2 saed90nm_max_lt/DFFASX1 saed90nm_max_lt/DFFASX2 saed90nm_max_lt/DFFNARX1 saed90nm_max_lt/DFFNARX2 saed90nm_max_lt/DFFNASRNX1 saed90nm_max_lt/DFFNASRNX2 saed90nm_max_lt/DFFNASRQX1 saed90nm_max_lt/DFFNASRQX2 saed90nm_max_lt/DFFNASRX1 saed90nm_max_lt/DFFNASRX2 saed90nm_max_lt/DFFNASX1 saed90nm_max_lt/DFFNASX2 saed90nm_max_lt/DFFNX1 saed90nm_max_lt/DFFNX2 saed90nm_max_lt/DFFSSRX1 saed90nm_max_lt/DFFSSRX2 saed90nm_max_lt/DFFX1 saed90nm_max_lt/DFFX2 saed90nm_max_lt/FADDX1 saed90nm_max_lt/FADDX2 saed90nm_max_lt/HADDX1 saed90nm_max_lt/HADDX2 saed90nm_max_lt/HEAD2X16 saed90nm_max_lt/HEAD2X2 saed90nm_max_lt/HEAD2X32 saed90nm_max_lt/HEAD2X4 saed90nm_max_lt/HEAD2X8 saed90nm_max_lt/IBUFFX16 saed90nm_max_lt/IBUFFX2 saed90nm_max_lt/IBUFFX32 saed90nm_max_lt/IBUFFX4 saed90nm_max_lt/IBUFFX8 saed90nm_max_lt/INVX0 saed90nm_max_lt/INVX1 saed90nm_max_lt/INVX16 saed90nm_max_lt/INVX2 saed90nm_max_lt/INVX32 saed90nm_max_lt/INVX4 saed90nm_max_lt/INVX8 saed90nm_max_lt/ISOLANDX1 saed90nm_max_lt/ISOLANDX2 saed90nm_max_lt/ISOLANDX4 saed90nm_max_lt/ISOLANDX8 saed90nm_max_lt/ISOLORX1 saed90nm_max_lt/ISOLORX2 saed90nm_max_lt/ISOLORX4 saed90nm_max_lt/ISOLORX8 saed90nm_max_lt/LARX1 saed90nm_max_lt/LARX2 saed90nm_max_lt/LASRNX1 saed90nm_max_lt/LASRNX2 saed90nm_max_lt/LASRQX1 saed90nm_max_lt/LASRQX2 saed90nm_max_lt/LASRX1 saed90nm_max_lt/LASRX2 saed90nm_max_lt/LASX1 ...}

not clear with your post...
So get_lib_cells gives the required result.. but you mention it is not listing some cells

I believe it should list out all available cells in the library - if it it is a bug in the tool

I think there should be a limit for size of lists in Design compiler. So it skips the remaining cells and puts "..." at the end of the list.

there might be many other libs used during the flow. Follow below procedure.

1. Get all the libs.
dc-shell :> set libs [get_libs *]
2. Get lib cells :
dc_shell :
foreach_in_coll lib $libs {
set lib_cells [get_lib_cells $lib/*]
foreach_in_coll lib_cell $lib_cells {
echo "[get_attr $lib_cell full_name]"
}

collect all the lib cells in the file and sort it . Now you get the required result. Check the syntax.

a simple "redirect" usage with "get_lib_cell" will also solve your purpose
