How can I remove module before writing whole netlist out

Maso

Hi,

I have a design top module "top". It have a sub module "add_sub".

I will write out whole netlist for top, but I don't want to write out add_sub.

How can I do this?

 Thanks a lot.

  •  In RC, you can do the following:

    foreach i [get_attr instances [find / -subdesign add_sub]] {

        set_attr unresolved true $i

    }

    write_hdl > top.vg

     

    The above script finds all instances of add_sub, and sets an "unresolved" attribute on each instance.  This TCL could, of course, be simplified if there is only one instance of add_sub.

    write_hdl will now omit the add_sub module from the netlist.
