EDA Algorithm Development: 避坑指南 (Pitfall Guide)

Core Philosophy

• Electronic Design Automation: Keep in mind that "Design cannot be automated" - human insight remains essential in the automation process.

Data Type Considerations

Coordinate Systems

• Use integer types for coordinates rather than floating-point
• Avoid floating-point representation for coordinates due to:
  • Energy inefficiency
  • Round-off errors that accumulate during computations

Integer Overflow Prevention

• Consider using 64-bit integers instead of 32-bit to prevent overflow problems in large-scale designs

Global Routing Challenges

High Fanout Nets

• Special handling required for nets with many connections
• Current suggestion: kd-tree data structure (investigation needed)

Clock Tree Synthesis

Bounded Skew Requirements

• Primary objective: Minimize total wirelength while maintaining skew bounds
• Trade-offs between skew control and wirelength optimization
