I am using Quartus Prime 16.0.2 to draw a block diagram. I connect different components with the node connector (in red box below):
It is unclear to me why sometimes a connector dot appears and sometimes it doesn't. For example, the connection between input pin D1 and the D-input on the left latch has fat connection dots at each end. The connection from the Q-output on the left latch to the D-input on the right latch has a dot on the left side but not on the right. How do I control whether the dot appears? I don't want it to appear except where a signal splits, such as the clock input on the bottom left.
