Description

Reports statistics on wire widths for route segments in the entire design, in the given set, or wholly within the given region. This is useful for quantifying widen_wire results. Each gapFill shape (used for wire widening) can only belong to one route segment.

The statistics include the following:

• The number of route segments (NRS) for each width and layer
• The length of route segments (LRS) for each width and layer
• The total number of route segments by layer
• The total length of route segments by layer
• The average width of the reported route segments
  This gives a quick measure for comparison when widening wires.

Arguments

-all	Reports on all nets. This is the default.
-exclude_type {[power][ground][clock]}
	Excludes the given net types from the report. By default, all net types are included.
-file s_fileName	Outputs the report to the given file.
-layers {s_layerName…}	Reports only on layers in the list. By default, all valid routing layers are reported.
-region {f_xlo f_ylo f_xhi f_yhi}
	Restricts reporting to the area given by the lower-left (f_xlo, f_ylo) and the upper-right (f_xhi, f_yhi) bounding box coordinates.
-set d_setObj	Reports on nets in the given set.

Examples

The following example shows how wire widths are reported.

For this example, the following would be reported for the three route segments:

report_wire_width_stats -set [get_selection_set]
NRS = Number of Route Segments
LRS = Length of Route Segments
+-------+-----------+-----------+-----------+-----------+
| Layer |      0.14 |      0.16 |      0.18 |    Total  |
+-------+-----------+-----------+-----------+-----------+
|       |NRS   LRS  |NRS   LRS  |NRS   LRS  |NRS   LRS  |
+-------+-----------+-----------+-----------+-----------+
|M1     |  1    0.52|  0       0|  0       0|  1    0.52|
|M2     |  0       0|  1    1.08|  1    1.28|  2    2.36|
+-------+-----------+-----------+-----------+-----------+
| TOTAL |  1    0.52|  1    1.08|  1    1.28|  3    2.88|
+-------+-----------+-----------+-----------+-----------+
The average width is .165
