Returns a Manhattan Route between 2 ports.

The references are straights, bends and tapers.

Parameters:

  • component – to place the route into.

  • port1 – start port.

  • port2 – end port.

  • cross_section – spec.

  • layer – layer spec.

  • bend – bend spec.

  • straight – straight spec.

  • start_straight_length – length of starting straight.

  • end_straight_length – length of end straight.

  • waypoints – optional list of points to pass through.

  • steps – optional list of steps to pass through.

  • port_type – port type to route.

  • allow_width_mismatch – allow different port widths.

  • radius – bend radius. If None, defaults to cross_section.radius.

  • route_width – width of the route in um. If None, defaults to cross_section.width.

  • auto_taper – add auto tapers.

  • on_error – what to do on error. If error, raises an error. If None ignores the error.

  • layer_transitions – dictionary of layer transitions to use for the routing when auto_taper=True.
