How can I design a 7400 (it has 4x NAND gates) so that I can place single NAND gates in the schematic editor?
What I've tried:
Using the parts/library editor I made a new component holding that 4 NAND. As the second step I wanted to assign the ICs pins (14). Assigning the pins to the 4 NANDs wasnt a problem but it wasnt possible to assign pin7 to GND and pin14 as Vcc because these pins havent been in the assignment list/editor. What did I wrong?
Thanks for your help
