i have vcc nets connected to multiple pins in schem through net alias VCC and two diff ground GND1 & GND2.. after netlisting i am able to see only gnd1 net but VCC n GND2 nets are missing. thr is no error in session log too!!any help on this?
Check Constraint Manager - Properties tab - Net - General Net Properties. Do the missing nets have a No Rat property defined ??
yes..this happens by default to power nets esp. long/multiple power nets or multiple gnd nets etc..after editing the pin properties i am able to see the ratsnest
