Bug #5402

Updated by tnt over 2 years ago

The gateware needs some improvements to provide all functions required by upper layer : 

 * 

  - Need some way to detect we have no signal (for instance, no pulse at all) 
 * 
  - Need some way to detect incoming AIS (all ones) 
 * 
  - The RX generated tick should still be generated even if no signal was ever received. 
    ATM it's off until we get a signal and then it continues even if we loose the signal, but it'd be better to have it from the start so that in a 'remote tick' confix, the tx side runs directly. Its phase will obviously be off for when we get a signal but that's not different from the caser where we loose signal and re-acquire ... 

 Put all in one issue because the hw changes will most likely be interlinked and have to be implemented/designed at once since they interact with the same part of the circuit (RX clock recovery mostly).
