The "flipped connection operator", or the "backpressure connection operator" between a producer and consumer.

For consumer :>= producer, each of producer's leaf members which are flipped with respect to producer are driven from the corresponding consumer leaf member Only producer's leaf/branch alignments influence the connection.

Symbol reference:

• ':' is the consumer side
• '=' is the producer side
• '>' means to connect from consumer to producer

The following restrictions apply:

• The Chisel type of consumer and producer must be the "same shape" recursively:
  • All ground types are the same (UInt and UInt are same, SInt and UInt are not), but widths can be different (implicit trunction/padding occurs)
  • All vector types are the same length
  • All bundle types have the same member names, but the flips of members can be different between producer and consumer
• The leaf members that are ultimately assigned to, must be assignable. This means they cannot be module inputs or instance outputs.

Additional notes:

• Connecting two util.DecoupledIO's would connect ready from consumer to producer, but leave bits and valid unconnected
