Tool/software: TINA-TI or Spice Models
There's another big in TINA
Since TI did not implement logical elements, but provide some dummies with TINA demonstration projects, I just copied a symbol from AND dummy for.. lets say a 3state buffer dummy; it does not matter.
I edited the macro, edited the symbol, renaming everything to "BUF3N".
But in the schematics the symbol name stays "AND2" as before the edit.
And I can not create a new symbol, because there is another bug, damaging the pin "invisible connection point's" coordinates, when the pin is touched, or a new pin is created.
