If you set the block routes to bi-directional, the SML generates properly.
Thanks Dave. I originally did not have deniedBlocks and several SML failed. Since the layout is designed for only one direction I (painstakingly) right-clicked each block, edit block, edit routing, select send/receive appropriately for every block.
?
All other pairs?display?aspect correctly with?deniedBlocks. Why would this single path/pair fail? I certainly will attempt this change but not knowing the reason doesn’t help my understanding. Can you tell me why?
