Choosing the Routing Mode
Routing can be performed in gridless or gridded mode.
- In gridless mode, edges of all shapes must be on the manufacturing grid.
- In strictly gridded mode, the centerlines of route segments must be on a routing grid, and the origins of vias must be placed on the via grid.
- In hybrid gridded mode, the router will try to stay on a routing grid. If there are off-grid pins in your design, then the router will attempt to connect those pins on the manufacturing grid. This is the default.
To specify the routing mode, use
set_route_on_grid -style {hybrid_gridded | manufacturing | strictly_gridded}
