Hi,
I have written TCL file and extract instances for cones.
the source file has multiple modules having same instances. for example :
module or3_55(A, B, C, z);
CLKBUF1 drc(.A (n_4), .Y (z));
endmodule
module nand2_248(A, B, z);
CLKBUF1 drc(.A (n_1), .Y (z));
endmodule
module(2681, L2684, L2687, L375)
or3_55 U1555(L2681, L2684, L2687, L375);
endmodule
now I want fanin of last module which has or3_55 above definition. I do this like that : "dc::all_fanin -to U1555/L375 -only_cells". It does not work.
I require basically fanin for U1555. how I get all instances ? It should go to above definition or3_55 and give answer its instances "drc" only.
Thanks
