    Save congestion maps ? Reply

    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]
    --------------------------------

    Cheers!
