Meaning
Diagrammatic representations document the logical connections and component properties of an electronic circuit within a specific design tool. An orcad capture schematic provides the master netlist that guides the physical layout of the printed circuit board. This document uses standardized symbols to represent resistors, capacitors, and complex integrated circuits.
Design Entry
Symbols are placed on the workspace and connected with wires to define the flow of electricity through the system. Within the orcad capture schematic, designers assign unique names to each net to track signals across multiple pages of the design. This organization is necessary for managing the complexity of modern smart devices with hundreds of connections.
Netlist Extraction
Automated tools convert the visual diagram into a text file that describes every electrical connection for the layout software. The orcad capture schematic ensures that the properties of each component, such as footprint name and part number, are included in this data. This file is the primary link between the logical design and the physical implementation.
Attribute Management
Properties assigned to each part in the schematic drive the creation of the bill of materials. An orcad capture schematic allows for the inclusion of supplier data and cost information directly on the design sheet. Keeping this information in the schematic ensures that the procurement team always has the latest specifications from the engineering team.
