Object Hugging
Since the design rules are all live during placement it is quite easy to hug a track to another
track or to wrap a track around an object. If the mouse is over an object where the route being
placed cannot travel then the route will follow the mouse path as closely as it legally can,
essentially hugging the barrier object.
Abandoning a Route
- If you want to abandon the route at the last committed (solid) segment then right click the
mouse.
- If you want to abandon the route at the mouse pointer then left click to commit up to mouse
pointer and then right click to terminate the track.
- If you want to abandon the route completely then hit the ESCAPE key.
Making Connections
If you are connecting directly to a pad then a left click of the mouse will complete the connection
and terminate route placement.
If you are connecting to a track then left click will commit the placement and right click will
terminate the route forming the connection. The same procedure applies if you are connecting
to a zone except that you must connect to the zone border.
Placing a Curved Route
Placing a route with curved corners can be helpful with signal integrity and net tuning or simply
for aesthetic reasons. In Proteus, you can switch to curved route placement by holding down
the CTRL key during route placement. Releasing the CTRL key will immediately switch back to
linear routing giving you the control to curve only specific parts of the route. The process of
placing the route is exactly the same as before, except we hold CTRL down on the keyboard for
curves. So:
1) Left Click the mouse to start the route.
2) Hold CTRL down to curve the corners and guide the route towards the destination pad
with the mouse.
3) Left click the mouse on the destination pad to terminate the route.
