Synopsys Totem 2026

Synopsys Totem 2026: Gold-Standard AMS Power Integrity Signoff

Synopsys Totem 2026 is the industry’s trusted gold-standard voltage drop (IR) and electromigration (EM) signoff solution for transistor-level and mixed-signal designs . The 2026 release introduces significant performance breakthroughs through Totem-SC, delivering up to 10x faster signoff for advanced analog/mixed-signal (AMS) designs .

Key New Features in Totem 2026

Elastic Distributed Computing (Totem-SC)

The major highlight is the introduction of elastic distributed computing, enabling AMS signoff tasks to achieve up to a 10x speedup by automatically distributing tasks across multiple compute nodes . Key innovations include:

• Intelligent Task Splitting: Automatically divides tasks based on circuit structure to optimize parallel granularity and reduce communication overhead .

• Distributed Memory Management: Optimizes cross-node data sharing to avoid redundant computation .

• Fault Tolerance & Elastic Scaling: Supports dynamic addition or removal of nodes, ensuring high reliability for long-running signoff tasks .

Cloud-Native & High-Capacity Analysis

Totem-SC leverages the SeaScape big-data elastic compute infrastructure, enabling :

• Near-instant start and near-linear scalability across thousands of CPU cores .

• Analysis of very large chips, including full HBM memories and CMOS image sensors (CIS) .

• Low per-core memory requirements, suitable for cloud-based execution .

TSMC Advanced Node Support

The 2026 release extends support for advanced process nodes, with Synopsys collaborating with TSMC to provide analog power integrity signoff for :

• TSMC A14: Collaborates with RedHawk-SC for digital power integrity and PathFinder-SC for ESD signoff .

• TSMC N2: Provides analog power integrity signoff at ultra-high capacity for large N2-based designs and embedded memories .
