    Buffer constant nets in RC Reply

    Hi guys,

    Some of my output pins are tied to ground, and that is causing problems in extraction. In dc_shell you could insert inverters/buffers in the constant lines to prevent this problem. I think it used to be called set_fix_multiple_port_nets or something with a buffer_constants option.

    Does RC have such capability or an attribute we could set?

    Thanks,

    There is a utility called insert_tiehilo_cell to replace constant nets with tie cells. To use it, you need to source the load_etc.tcl script first.

    Thanks that would work. I tried another way "remove_assigns" command worked for me since the assigns were in the RTL code.
