Varatharajan, you may get differing opinions on this one... So, let me
tell you why I don't connect 4 lines into a single node. A single line
drawn between two points represents a net [unless it's dangling :)]. If
you add a third line to the net, most schematic capture tools will
confirm the connection by placing a small indicator (dot, square,
etc...) at the intersection. By adding a forth line to the same
intersection, the tool does not have a way to confirm that the last line
is logically connected to the destination net. If you are fortunate
enough that the forth net comes from a single source, "most" sch capture
tools will report that net as dangling, whereby you can correct it. If
however the forth net comes from multiple sources (i.e. two other ICs,
discretes, etc...), it may not complain at all and leave both your net,
AND YOU, hanging!
Hope that helps.
Cheers,
Jim
