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.

Track

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

For example ‘track4’, gives

../_images/Options_track4.png

For example ‘track8’, gives

../_images/Options_track8.png

Cuts

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

\d+cuts

For example ‘3cuts’
