Simulation-based circuit-activity estimation for FPGAs containing hard blocks
Bibliographic record
Abstract
FPGAs are electronic devices that are programmable and can functionally perform equivalently to a number of other circuits. FPGAs are used for both rapid and cheap prototyping of new circuit designs as well as for replacing outdated chip models. Due to their complexity, circuits cannot be practically designed by hand; instead, specialized Computer Aided Design (CAD) software performs this complex task. A major concern for devices is power requirements, which can have adverse effects on both the environment and users. The power requirements of a circuit can be directly connected with its activity, which can be estimated by the CAD tools. In this work, we focus on the open source Verilog-To-Routing (VTR) CAD software and propose an improved activity estimation tool using VTR's synthesizer (Odin II) that extends beyond the capabilities of its current estimator (ACE2), such as proper black box activity propagation and support for circuits containing no clocks or more than one clock. Our results are experimentally evaluated with VTR's FPGA architectures and benchmark circuits.

Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
