Route Options

The router has some options to ease routing. Both connectivity routes and directed routes have options. Options are separated by a comma.

Sort options

These options specify which rectangle to route from. They are useful for connectivity route where the start rectangles are not specified.

onTopB

Put the bottom rectangle as start rectangle [[graphics/Options_onTopB.png]] ##### onTopT Put the top rectangle as start rectangle [[graphics/Options_onTopT.png]] ##### onTopR Put the right rectangle as start rectangle [[graphics/Options_onTopR.png]] ##### onTopL Put the left rectangle as start rectangle [[graphics/Options_onTopL.png]]

Offset

These options can offset the routing rectangle to avoid nearby routings

offsethigh

Track

‘track’ can be used to specifiy how many grids the route is offset. It uses “ROUTE” and “horizontalgrid”.

For example ‘track4’, gives [[graphics/Options_track4.png]]

For example ‘track8’, gives [[graphics/Options_track8.png]]

Cuts

The number of cuts used by the route can be modified. Default is two cuts for the horizontal via.
