Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single topological structure is used for IP core, then the design is simple, but it cannot adapt to different requirements and may compromise signal integrity when driving multiple loads
Solution Approach 1:
The patent divides the topological structure into two distinct parts: a first topological structure for driving first loads and a second topological structure for driving second loads. Each topological structure can be independently configured and optimized, allowing the system to adapt to different requirements without increasing overall complexity excessively. The segmentation enables modular design where each part can be selected based on specific application needs.
Solution Approach 2:
The patent introduces the concept of selectable topological structures where the system can dynamically choose between different configurations. The control unit can select which topological structure to use based on the specific requirements, making the system flexible and adaptable rather than fixed. This dynamic selection capability allows the same IP core to serve multiple purposes with different load requirements.
2Adaptability or versatility
If multi-stage signal lines are used to drive multiple loads, then the adaptability increases, but the impedance continuity and signal integrity may be compromised
Solution Approach 1:
The patent applies different topological structure characteristics to different parts of the system. The first topological structure is optimized for driving first loads with specific impedance characteristics, while the second topological structure is optimized for second loads. Each part has locally optimized properties that match its specific requirements, ensuring signal integrity within each segment while maintaining overall system adaptability.
Solution Approach 2:
The control unit acts as an intermediary that selects and manages the different topological structures. It ensures proper configuration and switching between different topological structures, maintaining impedance continuity and signal integrity by coordinating the operation of multiple topological structures rather than allowing them to conflict.

AI summary
Disclosed in the embodiments of the present disclosure is a topological structure for an IP core. The topological structure comprises a first topological structure and a second topological structure, wherein the first topological structure comprises a drive chip, multi-level first signal lines and at least two first loads, a signal output end of a previous-level first signal line being connected to signal input ends of two next-level first signal lines which are connected in parallel, a signal input end of a first-level first signal line being connected to a signal output end of the drive chip, and an output end of each last-level first signal line being connected to a first load; and the second topological structure comprises a plurality of branch structures, each of which comprises at least one second load, a signal input end of each branch structure being connected to a signal output end of a last-level first signal line of the first topological structure. A new topological structure is provided for an IP core, so as to realize diversified IP core topological structures to adapt to different requirements.
