map type
Where type is one of the following:
obstructions
congestion
estimate
none
routes
noroutes
The map command specifies how to draw the routing visualization in the graphics window. The drawing consists of a background depicting the circuit layout, and a foreground depicting the routes. The first four types listed above are different background types. The obstructions map is the default. It displays all obstructions in light gray and terminal pins in dark gray, one square per track pitch. Because obstructions are typically caused by cell geometry, the background gives a rough indication of the cell layout. The congestion map is a color-graded map of the congestion due to routes and obstructions. It takes into account only routed nets, and so will update as routing progresses. The estimate map is a color-graded map of the estimated congestion, and does not depend on actual route solutions. It is formed by finding the bounding box of each net, including all terminals, and spreading the integer length of the most likely route over the area of the bounding box. The type none displays no background at all underneath the routes. The option routes or noroutes displays or cancels the display of routes on top of the background.The background map display is also modified by the stage1 debug and stage2 debug command options, which display additional information about the route search strategy on top of the background.
map is implemented as a built-in command in qrouter, only in the Tcl version.
