Mixed-signal systems present unique challenges due to the coexistence of analog and digital components within a unified design. To address these challenges, high-level design methodologies are increasingly employed to manage complexity and enable early system validation. High-Level Synthesis (HLS) plays a critical role in this context by allowing designers to specify digital functionality at a higher abstraction level—such as SystemC—and automatically generate synthesizable RTL.

This presentation explores a methodology that integrates SystemC for digital modeling and SystemC AMS for analog/mixed-signal behavior, enabling holistic system-level design and simulation. By modeling the complete system at a high level, designers can validate interactions across domains, refine architectural decisions, and identify issues early in the design flow. Once verified, digital components can be synthesized using HLS, streamlining the path from algorithm to hardware. This approach promotes better abstraction, design reuse, and coherence between system-level modeling and implementation in heterogeneous mixed-signal systems.
