Abstract
As global technological competition intensifies, the challenges in chip design are becoming increasingly complex, highlighting the urgent need for open-source EDA (Electronic Design Automation) platforms. The introduction of open-source EDA tools can lower the barriers to chip design, foster scientific research, and promote talent development. However, issues such as a limited user base and insufficient contributions need to be addressed. This study investigates the 2022 version of Icarus Verilog, providing a detailed introduction to its system principles and analyzing its internal architecture and module composition. Additionally, we validate its preprocessing, compilation, and simulation functionalities by testing the ZUC-128 cryptographic algorithm on the LicheePi 4A, a high-performance RISC-V Linux development board based on the Lichee Module 4A and powered by the TH1520 core. Experimental results indicate that Icarus Verilog offers flexible open-source characteristics and a wide range of applications, reducing R&D costs and providing high utility. This research fills a gap in the domestic study of Icarus Verilog and offers valuable insights for the future development and optimization of open-source EDA tools.

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 it
