Abstract
Modern FPGAs are able to implement complex systems such as Systems-on-Chips (SoCs) and Networks-on-Chips (NoCs). Appropriate NoC topology choices for ASICs have been investigated and typically topologies that can be easily mapped to a two-dimensional fabric are used to reduce chip area and ensure electrical characteristics. However, for FPGAs, each device's size and routing fabric are fixed. Since these resources exist independent of use, the choice of topology is only limited by the performance of the NoC itself. In this work, we investigate how topology characteristics impact a NoC's performance on an FPGA. From this analysis, we have created an analytical model that describes the maximum operating frequency of a NoC as a function of the topology's network parameters. This model is in the form of a simple equation that is accurate to within 4.68% across a range of topologies, chip sizes, and device families. It demonstrates how an FPGA's prefabricated routing interconnect provides increased freedom in the selection of application-specific topologies. Furthermore, it can also be used by designers for topology design space exploration before implementation.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
