In my dream universe where pin/slot swapping and a central heavy database exist, that would be: nand8 : [A=1,B=2,C=3,D=4,E=5,F=6,G=11,H=12],Y=8,Vcc=14,GND=7 : TI : SN74ALS30N : DIP-14-300.fp > example of 7401 nand2 : ([A=2,B=3],Y=1),([A=5,B=6],Y=4),([A=8,B=9],Y=10),([A=11,B=12],Y=13),Vcc=14,GND=7 : TI : SN74ALS01N : DIP-14-300.fp Longer example of 7400: nand3 : ([A=1,B=2],Y=3),([A=4,B=5],Y=6),([A=9,B=10],Y=8),([A=12,B=13],Y=11),Vcc=14,Gnd=8 : TI : SN74ALS00N : DIP-14-300.fp nand3 : [A=1,B=2],Y=4,Vcc=5,GND=3 : TI : SN64AHC1G00 : SOT-23-t.fp and elsewhere: nand3 : NAND-2-1.sym nand3 : NAND-2-E.sym nand3 : ORN-2-1.sym nand3 : ORN-2-E.sym and elsewhere: TI : SN64AHC1G00 : Digikey : 296-1087-1-ND and elsewhere: Digikey : 296-1087-1-ND : 1 : 0.4000 Digikey : 296-1087-1-ND : 25 : 0.3124 Digikey : 296-1087-1-ND : 100 : 0.2200 Digikey : 296-1087-1-ND : 250 : 0.1500 We still have the problem of hidden power nets, though. I suppose we could have a separate database for those, per part: SN74ALS00N : Vcc : 4.75 : 5.25 SN74ALS00N : GND : 0 : 0 SN74LV00N : Vcc : 1 : 5.5 SN74LV00N : GND : 0 : 0 _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
