Choosing Place » Bus from the Schematic Editor main menus.Availabilityīuses are available for placement in the Schematic Editor only by: SummaryĪ Bus is a polyline object that represents a multi-wire connection and is an electrical design primitive. Bus Entries only need to be used if you want to rip different bus elements from both sides of the Bus.Ī Bus is a polyline object that is used, in conjunction with other connected objects, to define the connection of multiple nets. A Port named the same as the Bus if it is leaving this sheetĪll of the elements shown in the image above must be included to create a valid Bus.A Net Label on each of the individual nets.To create a valid bus, it must include all of these elements (as shown in the images below): Buses cannot be used to bundle an unrelated set of nets, such as the nets Enable, Read and Status, Signal Harnesses are used to do this, as explained below. For example, the nets Control1, Control2 and Control3 can be bundled into the bus Control. Their core requirement is that each net in the bus is named with a common base name, followed by a numeric identifier, as shown in the images below. This can be helped by bundling nets into Buses or Signal Harnesses.īuses are used to bundle a series of sequential nets, for example, an address bus or a data bus. This is particularly important when connecting between sheets as this is when both the designer and the reader can most easily get confused. Not only from the perspective of the designer creating the connectivity but also from the perspective of the reader that has to interpret and understand the schematic. Parent page: Creating Circuit Connectivity in Your SchematicsĪ common challenge in a large design is keeping the nets manageable.
