Veylon Systems leverages the power of LLM-based AI agents and advanced commercial simulation technologies to accelerate mixed-signal modeling workflows. Our platform ingests transistor-level SPICE netlists, functional specifications, and existing customer IP or behavioral models to automatically generate accurate, simulation-ready models in SystemVerilog Real Number Modeling (SV-RNM) and Verilog-AMS. The generated models support custom user-defined net types and seamlessly integrate into existing digital verification environments, enabling faster design verification through efficient Digital Mixed-Signal (DMS) simulation.
