Connects a bundle of ports, allowing steps which create waypoints at arbitrary, non-manhattan angles.

Parameters:

  • ports1 – ports at the start of the bundle.

  • ports2 – ports at the end of the bundle.

  • steps – a list of steps, which contain directives on how to proceed with the route. “x”, “y”, “dx”, “dy”, “ds”, “exit_angle”, “cross_section”, “connector”, “separation”. The first route, between ports1[0] and ports2[0] will take on the role of the primary route, and other routes will follow, given the bundling logic. It is assume that both ports1 and ports2 are sorted. cross_section: the default cross-section of the bends. Then the specified connector may also use this information for straights in between.

  • bend – the default component to use for the bends.

  • connector – the default connector to use to connect between two ports.

  • start_angle – if defined and different from the angle of port1, will cap the starting port with a bend, as to exit with this angle.

  • end_angle – if defined, and different from the angle of port2, will cap the ending port with a bend, as to exit with this angle.

  • end_connector – specifies the connector to use for the final straight segment of the route.

  • end_cross_section – specifies the cross section to use for the final straight segment of the route.

  • separation – specifies the separation between adjacent routes.

  • kwargs – added for compatibility, but in general, kwargs will be ignored with a warning.

Returns:

List of Routes between ports1 and ports2.
