In KiCad, multi-sheet schematics are organized hierarchically, offering a structured approach to design. This hierarchical structure consists of a single root sheet, with additional sheets created as subsheets either of the root sheet or of another subsheet. This setup allows for a clear organization of the schematic, making it easier to understand and maintain.

When creating a hierarchical schematic in KiCad, it's essential to start from the root sheet and then progressively build out the subsheets. Each subsheet represents a distinct module or functional block of the circuit. Within each subsheet, the circuitry specific to that module is drawn, and necessary connections are made.

To establish connections between sheets in the hierarchy, several methods can be used. Hierarchical pins and labels facilitate connections between nets in a subsheet and nets in the parent sheet. These hierarchical pins and labels act as interfaces, allowing signals to flow between different levels of the hierarchy seamlessly. Additionally, global labels enable connections between any two nets within the hierarchy, providing flexibility in establishing inter-sheet connections.

By carefully organizing the schematic as a hierarchical design, you can enhance legibility, reduce repetitive drawing tasks, and streamline the design process. This structured approach not only improves readability but also simplifies troubleshooting and modifications as the design evolves.

In the context of PCB design, constraints, predefined sizes, net classes, custom rules, and violation severity are all related to the specification and management of design rules and parameters. Here's an explanation of each:

1. Constraints:

   - Constraints refer to the rules and requirements that dictate how the PCB layout should be designed. These constraints may include electrical, mechanical, manufacturing, and assembly considerations.

   - Electrical constraints may specify parameters such as trace widths, clearance between traces, impedance control, and signal length matching.

   - Mechanical constraints may specify the board size, component placement restrictions, mounting hole locations, and keep-out areas.

   - Manufacturing constraints may specify design rules related to the fabrication process, such as minimum drill sizes, minimum annular ring, and solder mask expansion.

   - Constraints ensure that the PCB design meets functional requirements, complies with industry standards, and can be manufactured and assembled reliably.

2. Predefined Sizes:

   - Predefined sizes are standard dimensions and parameters that are predefined and commonly used in PCB design.

   - These sizes may include standard board sizes (e.g., 100mm x 100mm, 150mm x 100mm), component footprints, pad sizes, drill sizes, and other geometric dimensions.

   - Using predefined sizes helps streamline the design process, ensures consistency across designs, and facilitates compatibility with manufacturing processes and component libraries.

3. Net Classes:

   - Net classes are groups of nets that share common electrical characteristics or design requirements.

   - By assigning nets to net classes, designers can apply specific design rules and constraints to all nets within the class collectively.

   - For example, high-speed signal nets may be grouped into a net class with specific impedance control requirements, while power and ground nets may be grouped into another net class with different clearance and width constraints.

   - Net classes streamline the design process, improve organization, and facilitate the application of consistent design rules across the PCB layout.

4. Custom Rules:

   - Custom rules allow designers to define and enforce specific design requirements and constraints beyond the default settings provided by the PCB design software.

   - These rules may include unique constraints tailored to the specific needs of the design, such as special clearance requirements for sensitive components, specific routing directives for critical signals, or unique design constraints for a particular application.

   - Custom rules provide flexibility and enable designers to address complex design challenges and unique requirements effectively.

5. Violation Severity:

   - Violation severity refers to the level of importance or criticality assigned to design rule violations detected during the design verification process.

   - Design rule violations are flagged by the PCB design software when a design element (such as a trace, pad, or component) fails to meet specified constraints or rules.

   - Violation severity categorizes violations based on their impact on design integrity, manufacturability, functionality, and reliability.

   - Severity levels may include warnings for minor violations that do not significantly impact performance, errors for violations that require correction but do not prevent the design from being manufactured, and critical errors for violations that must be addressed immediately to ensure the design's functionality and reliability.

In summary, constraints, predefined sizes, net classes, custom rules, and violation severity are all critical aspects of PCB design rule management and enforcement. These elements ensure that the PCB design meets functional requirements, complies with industry standards, and can be manufactured and assembled reliably.
