Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If software-based modeling tools are used, then development cost and time are reduced, but the system cannot handle high-speed data rates and is non-deterministic
Solution Approach 1:
The system segments functionality into software-based modeling components and hardware-based simulation components. Software handles high-level system modeling and control, while dedicated hardware processors handle time-critical physical layer simulations and high-speed data processing, allowing each to operate in its optimal domain
Solution Approach 2:
A hardware interface layer acts as an intermediary between software modeling tools and hardware-based simulation systems. This interface enables deterministic data exchange and synchronization, allowing software controllers to manage hardware resources while maintaining real-time performance guarantees
2Reliability
If hardware-based modeling systems are used, then deterministic simulation and high-speed data handling are achieved, but data capture and analysis become complex due to differing data formats
Solution Approach 1:
The system creates software-defined copies of hardware data structures that mirror the actual hardware data formats. Software analysis tools operate on these copied structures, which can be manipulated without affecting the underlying hardware data flow, simplifying analysis while maintaining hardware performance
Solution Approach 2:
The data handling system combines multiple data format representations into a unified composite structure. Hardware generates data in native formats, which are simultaneously preserved for hardware processing and converted to software-friendly formats for analysis, creating a multi-format data system that serves both domains
3Manufacturing precision
If multiple iterations of hardware creation and testing are performed, then design quality improves, but development cost and time increase significantly
Solution Approach 1:
The system performs preliminary hardware-based simulation and testing in a virtual environment before actual hardware fabrication. Designers can iterate through multiple simulation cycles using hardware models, validate designs, and identify issues before committing to expensive physical prototypes, reducing the number of actual hardware iterations needed
