How to generate WSPs in a row region?

Use the options on the Setup tab of the Auto P&R assistant to generate WSPs in row regions. 

1. Select Create Width Spacing Patterns to generate WSPs in the selected row region.
2. Select a Top Layer and a Bottom Layer to specify the routing layer range for which WSPs are to be created. WSP tracks are inserted in these and all intermediate layers.
3. In #Gate Tracks, specify the number of gate tracks to be accommodated within a WSP track period. The default is 2. This value impacts the WSP period. Gate tracks are required for poly gate routing. 
4. In Gate Track Width, specify the number of gate tracks to be added at the top and bottom of each row. The default value is 2, which specifies that two gate tracks are to be added to the top and bottom of each row.
5. In Gate Track Spacing, specify the spacing between gate tracks. Each WSP track must accommodate the given number of gate tracks of the specified width and spacing. If the specified track width exceeds the default, specify a wider spacing value.
6. Specify the width of source and drain tracks in the S/D Track Width field.  
7. In #S/D Tracks, specify the number of source and drain tracks to be accommodated in each WSP track period. Select either S/D Track Width or #S/D Tracks and specify a value. The default value is automatically calculated based on the layer constraints and area of the source and drain pins.

8. Click Generate.
