Legacy Node to Advanced Silicon: Schematic Migration in Cadence Virtuoso Studio

In today’s fast-paced semiconductor industry, technology nodes evolve quickly—yet analog designs often have long, productive lives. A carefully tuned amplifier, data converter, or IP block can often be reused across multiple process nodes and even across different foundries. This is where  schematic migration becomes essential. Schematic migration is now a crucial strategy for modern analog design reuse. 

Schematic migration involves transferring a schematic from a source technology (source PDK) to a target technology (target PDK) while maintaining:

• Circuit topology and hierarchy
• Device intent and parameter relationships
• Connectivity and bulk handling
• Readiness for simulation

In Virtuoso Studio, schematic migration is part of the Custom Design Migration flow, which also includes layout migration. The schematic phase sets the foundation by creating a clean, well-mapped, connectivity-accurate target schematic that can later guide layout migration and verification.

Design teams depend on schematic migration for several practical reasons:

1. Advancing technological nodes
2. Porting across foundries
3. Reusing IP and scaling products
4. Reducing risk and saving time

Virtuoso Schematic Migration directly addresses these issues by automating repetitive tasks while allowing designers to retain control over key decisions.

Schematic migration is now a crucial strategy for modern analog design reuse.

With Cadence Virtuoso Schematic Migration, designers can:

• Confidently transfer designs across different technologies
• Minimize manual effort and migration risks
• Preserve connectivity, parameters, and simulation intent
• Expand migration from individual cells to entire libraries

Whether upgrading nodes, changing foundries, or reusing proven IP, schematic migration enables faster progress without compromising quality, promising quality.
