    RTL compiler command for retaining design hierarchy Reply

     Hi,

    Is there a command in RTL compiler which can force the synthesizer to retain original hierarchy of the design, like there is in Xilinx ISE for instance?

     

    Thanks.

     Hi dkhan,

     I just used the RC apropo command and assume one of the following attribute is what you are looking for

     

    rc:/> apropo ungroup
    Commands matching search string:
      edit_netlist ungroup
      ungroup

    Commands with help text matching search string:
      ungroup

    Commands with option text matching search string:
      edit_netlist
      edit_netlist ungroup
      ungroup

    Attributes matching search string:
      auto_ungroup (root)
      auto_ungroup_min_effort (root)
      auto_ungroup_ok (subdesign)
      dp_ungroup_separator (root)
      ungroup (hdl_arch)
      ungroup (hdl_comp)
      ungroup (hdl_impl)
      ungroup (hdl_inst)
      ungroup_ok (instance)
      ungroup_ok (subdesign)
      ungroup_separator (root)

    Attributes with help text matching search string:
      auto_ungroup (root)
      auto_ungroup_min_effort (root)
      auto_ungroup_ok (subdesign)
      dp_ungroup_separator (root)
      ungroup (hdl_arch)
      ungroup (hdl_comp)
      ungroup (hdl_impl)
      ungroup (hdl_inst)
      ungroup_ok (instance)
      ungroup_ok (subdesign)
      ungroup_separator (root)

    I am assuming you need

     set_attr auto_ungroup false /

     

    gh-
