BUSINESS BENEFITS

Signoff analysis reduces project risk by avoiding costly errors in silicon. Accurate multiphysics simulation improves design performance by eliminating wasteful margin with better silicon correlation.

Ansys RedHawk-SC’s trusted multiphysics signoff analysis is a powerful way to reduce project and technology risk. RedHawk’s algorithms are certified accurate by all major foundries for all finFET processes and are proven in thousands of tapeouts.

The speed and capacity of RedHawk’s cloud-native SeaScape™ architecture enable ultra-large, full-chip power analyses by enlisting thousands of CPU cores with modest memory requirements. And RedHawk-SC’s advanced power analytics capabilities will calculate the timing impact of IR-drop, with coverage optimized to maximize possible activity scenarios.

These broad, silicon-correlated simulation results give designers the confidence they need to achieve higher performance and lower power by avoiding wasteful and expensive overdesign.

Thermal analysis and multi-die system analysis is enabled with the RedHawk-SC Electrothermal option, which adds full-system thermal and power integrity co-simulation for chips and 2.5D/3D IC packages, including package signal integrity and thermal-mechanical stress and warpage.

5G network infrastructure design

Comprehensive voltage drop, electromigration and electrothermal reliability signoff for SoC and 3DIC co-design

Ansys RedHawk-SC’s breakthrough SigmaDVD™ technology and advanced power analytics deliver very high coverage for capturing dynamic power supply noise, thereby avoiding frequency loss due to unexpected dynamic voltage drop (DVD). RedHawk-SC generates Chip Power Models (CPMs) and sophisticated Reduced-Order Models (ROMs) for high-accuracy hierarchical analysis of single chips and multi-die 2.5D/3D ICs. A rich GUI and ‘what-if’ capability. It analyzes thermal-aware current density in both signal and power net and provides statistical electromigration budgeting. Both vector and vectorless activity inputs are supported with advanced analytic capabilities that evaluate the robustness of power distribution networks.

RedHawk-SC is integrated with Synopsys PrimeTime™ timing signoff and Synopsys PrimeClosure™ to automatically optimize voltage drop ECOs without negatively impacting circuit timing.

 

Key Features

Dynamic and static voltage drop signoff with SigmaDVD technology for comprehensive coverage and root-cause analysis of all dynamic voltage drop instances and advanced power analytics to assess the quality of power distribution networks.

Current density and thermal-aware electromigration (EM) analysis for both power supply metal and signal interconnect with statistical EM budgeting.

Full-coverage dynamic voltage drop (DVD) diagnostics, calculated with SigmaDVD technology, identify switching aggressors as targets for optimizing IR drop without negatively impacting design timing.

AnsysGPT for Semiconductors provides immediate access to over 20 years of technical support information and design flow guidance through agentic learning.

Hierarchical analysis of large System-on-Chip (SOC) or multi-die 3D-ICs is enabled with Ansys Chip Power Models (CPMs) and RedHawk-SC reduced-order models (ROMs).

Multi-scenario activity patterns provide comprehensive coverage to identify dynamic power supply noise and avoid voltage drop escapes that cause frequency loss. These can be generated automatically (vectorless) or can be loaded by the customer (FSDB, VCD, etc.).

RedHawk-SC offers a rich GUI interface to display results of its Advanced Power Analytics and to enable What-If analysis of a power distribution network. It can also provide instantaneous feedback on the voltage drop effects of cell swapping and sizing for incremental  IR ECO fixing.
