From 61863b9e4a5b0ef08adc72dd592ed17c253aaa73 Mon Sep 17 00:00:00 2001 From: ErinXU2004 Date: Fri, 19 Dec 2025 17:28:12 +0000 Subject: [PATCH 1/6] Port sweep code from OpenFASOC and fix import paths MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 1: File Porting - Ported 35+ files from OpenFASOC/glayout/flow/blocks/elementary/LHS - Core engines: run_dataset_multiprocess.py, elhs.py, run_lhs_files.py - Cell implementations: transmission_gate.py, fvf.py, lvcm.py, current_mirror.py, diff_pair.py, opamp.py - Evaluation framework: evaluator_wrapper.py, verification.py, physical_features.py - Analysis tools: analyze_dataset.py, assemble_dataset.py, dataset_curator.py - Documentation: HowToRun.md, multiple README files - Test files and utilities Phase 2: Path Adjustments - Fixed 97 import statements across 15 Python files - Changed glayout.flow.* โ†’ glayout.* (blocks, pdk, primitives, routing, spice) - Changed glayout.pdk.util.* โ†’ glayout.util.* - Modified robust_verification.py to auto-detect PDK paths - Removed hardcoded path, added OpenFASOC fallback location Testing: - Successfully loaded 3464 parameter combinations - Script initializes and starts dataset generation - DRC, LVS, PEX framework validated Infrastructure: - Added Genv/ to .gitignore (virtual environment) Next: Phase 3 -
