Save congestion maps ?

archive

Hi all,

Is it possible to save congestion maps in any format (not screendumps) ?
I wish to load up the congestion map independent of the Nanoroute tool and view later..However, if this is not possible, I wish to load up only the congestion maps through Nanoroute (without performing the global route again).

Any help appreciated,
Cheers,
Prasanna

  • Hi Prasanna,

    Congestion map from NanoRoute can be saved as a REF file and imported back into Encounter. I have enclosed the
    following section from NanoRoute Reference Manual :
    [b][i]pdi save_design [view_name] [-ref my_design.ref][/i][/b]
    Saves the design onto disk. The design must have been imported with pdi import_design or created by performing routing.

    Argument

    [b][i]view_name[/i][/b] - Specifies the view name of the design.
    If you do not specify a view name, NanoRoute
    uses the last view opened.
    [i]
    [b]-ref -my_design.ref[/b] [/i] Saves an ASCII format representation of the congestion map that Encounter can read.

    Example

    The following command saves the design to an ASCII file named routed.ref.

    [i] pdi save_design -ref routed.ref[/i]

    The .ref file lists each global routing cell (gcell) on a separate line, in the following format:

    gcell_1 (llx, lly) (x_tracks_used / x_tracks_total, y_tracks_used / y_tracks_total)
    gcell_2 (llx, lly) (x_tracks_used / x_tracks_total, y_tracks_used / y_tracks_total)

    For example,

    GRC(2504.28, 19.68) (5/29, 10/20)
    GRC(24.6, -0.08) (1/0) (1/0, 1/19)[i][/i]
