1Productivity
If parallel computation is used to optimize PCB circuits, then optimization efficiency is improved, but system complexity increases
Solution Approach 1:
The patent divides the PCB circuit optimization into independent tasks that can be distributed across multiple processors. Each processor handles specific portions of the optimization, such as different frequency ranges or circuit sections, enabling parallel computation while maintaining manageable complexity through task segmentation.
Solution Approach 2:
The patent employs a mesh architecture where processors can serve multiple functions - they can act as computation nodes, data storage points, or communication relays. This multi-functionality reduces the need for specialized hardware components, thereby managing system complexity while enabling efficient parallel optimization.
2Loss of time
If mesh architecture is used for circuit optimization, then convergence time is reduced, but resource management complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where processors report their computation status and resource utilization levels to the mesh control block. This enables dynamic adjustment of resource allocation, allowing the system to converge faster by directing resources to critical optimization tasks while managing complexity through automated feedback-driven resource management.
Solution Approach 2:
The mesh architecture enables processors to autonomously manage their own resource allocation and computation tasks. Each processor can independently determine when it has completed its optimization tasks and when additional resources are needed, reducing the burden on central control systems and simplifying overall resource management while maintaining fast convergence.
3Measurement precision
If multiple processors are allocated for optimization, then calculation fidelity is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the optimization calculation into distinct tasks that can be distributed across multiple processors. Each processor performs specific calculations, such as impedance analysis for different frequency ranges or different PCB layers, enabling high calculation fidelity through specialized computation while simplifying manufacturing by using standardized processor modules.
Solution Approach 2:
The patent utilizes parameter changes in the mesh architecture to optimize calculation fidelity. By dynamically adjusting parameters such as frequency ranges, precision levels, and computational depth based on the specific PCB design requirements, the system achieves high accuracy without requiring complex hardware configurations, thereby easing manufacturing.

AI summary
Systems and methods provide circuit optimizations using a mech architecture of an IHS (Information Handling System). A control block operated by a CPU of the IHS determines availability of mesh resources, including resources of a removeable processor of the IHS. The control block reserves available resources of the removeable processor for use in a circuit optimization. The control block assigns a portion of the circuit optimization to the removeable processor. A mesh client operated by the replaceable processor calculates a result by processing the assigned portion of the circuit optimization. The mesh client also tracks the use of resource of the removeable processor during the calculation of the assigned portion of the circuit optimization. The results of the calculation and a log specifying the tracked use of the resources of the removeable processor are transmitted to the control block to determine updates to the mesh resources that are reserved.
