Does anyone have a handy way of reporting a list of flip flops by hierarchy in DC? I'm looking to do it interactively in DC while the ddc is loaded.

Thanks for your help
 

I think you may need the "get_cells" command and use the "-filter" option. Please "man get_cells" for detail.
Or you can write a TCL script to do it, using the DC/PT "attribute".
 

GeT_cells -hier -filter "is_sequential == true"
 

get_cells -hier -filter "is_sequencial == true && is_hierarchical == false" will give you all the leaf cells.

Note: -hier and is_hierarchical are two different attributes.
