* Any lower case suffix is ignored. This is so you can, place four discrete NAND gates on the schematic called U1a, U1b, U1c and U1d. They will netlist into a single footprint named U1. | * Any lower case suffix is ignored. This is so you can, place four discrete NAND gates on the schematic called U1a, U1b, U1c and U1d.

- | The **net**= attribute is used to create power/ground and arbitrary nets. Please see the [[gEDA:na_howto|net= attribute mini-HOWTO]] for more info. When this attribute is inside a symbol, it is used to create nets. When this attribute is attached to an instantiated component (in a schematic), then the **net**= can also be used to create new nets and can used to override existing nets. | + | The **net**= attribute is used to create power/ground and arbitrary nets.
