AutoVSR presents an automated visual-to-symbolic generation framework using Vision Language Models (VLMs). It reconstructs schematics into an executable intermediate representation (Executable IR) and applies a symbolic solver for reasoning, improving accuracy by 30.01–59.45% and 41.96–51.84%, and outperforming closed-source VLMs in inference cost and efficiency.","AutoVSR: Automatic Visual-to-Symbolic Reasoning for Symbolic Expression  \nGeneration from Circuit Schematic  \nZhe Xiao * 1 Longfei Li * 1 Xu He † 1 Haoying Wu 2 Zixing Zhang 1 Mingyu Liu 3  \narXiv :2607 . 1 1338v 1 [ cs .AI] 13 Jul 2026  \nAbstract  \nSymbolic expressions can effectively characterize and predict circuit behavior, but deriving them directly from circuit schematics is challenging. This process requires accurate visual-to-symbolic construction of circuit structure from images and correct multi-step symbolic derivation, both of which impose strict correctness requirements. This work proposes AutoVSR, an automated framework for visual-to-symbolic generation of circuit expressions using Vision Language Models (VLMs) .  \nBy reconstructing circuit diagrams into an executable intermediate representation (Executable IR) and leveraging a symbolic solver for reasoning, AutoVSR significantly improves the accuracy of symbolic expression generation. AutoVSR introduces two key innovations: an IR construction method guided by component rule retrieval and verification-based feedback, and a symbolic solver implemented as a planning agent equipped with a symbolic tool library for reliable multi-step derivation. Compared with end-to-end VLM approaches and specialized methods on the main symbolic expression generation task, AutoVSR achieves accuracy improvements of 30.01– 59.45% and 41.96–51.84%, respectively. Moreover, AutoVSR surpasses closed-source state-ofthe-art VLMs in inference cost and computational efficiency.

AutoVSR Framework Workflow & Performance Results  \nmanagement in electronic systems (Hao et al., 2021) . To meet performance requirements such as stability and dynamic response, engineers often rely on symbolic analysis to characterize and predict circuit behavior during the design process (Gielen et al., 1994) . A key step in symbolic analysis is to convert the structural information in visual circuit schematics into computable symbolic expressions that describe circuit behavior, such as input–output relationships and related analytical forms including transfer functions (Gielen & Sansen, 1991) . In practice, obtaining these expressions requires interpreting schematic images to identify components and recover connectivity, followed by stepby-step symbolic derivation and simplification. However, this expertise-dependent workflow is labor-intensive. Therefore, an automated visual-to-symbolic reasoning framework  \nis needed to bridge schematic images and symbolic expressions, improving efficiency and shortening design cycles.  \nThe emergence of multimodal large language models (MLLMs) has brought new opportunities to circuit-related tasks (Chen et al., 2024) . Current work mainly falls into two categories. (1) Circuit topology generation and reconstruction. These works focus on inferring the connectivity among circuit components, such as recovering netlists from schematics (Huang et al., 2025 ; Bhandari et al., 2025 ; Kulkarni et al., 2025) or synthesizing new circuit topologies (Vijayaraghavan et al., 2025 ; Gao et al., 2025) . (2) Assisted circuit sizing and optimization. Under a fixed topology, these works optimize device sizes and bias parameters (Yin et al., 2025 ; Karthik Somayaji & Li, 2025), typically by leveraging MLLMs to guide
