GloryGrid®
GloryGrid is an early power-grid assessment and optimization tool—the core component for power distribution within the τ-Aware ToolFramework. Facing the rising complexity of power-delivery design under the new scaling paradigm, GloryGrid moves power-network planning left into the early stages of chip design, covering the pre-placement through pre-PG-route stages.
Key Features
Automatically generates power-network patterns for 2D/2.5D/3D architectures based on user constraints.
Supports static and dynamic IR-drop analysis, PG EM analysis, and shortest-path-resistance analysis to quantify and evaluate power-scheme robustness.
Supports open/short checking of power networks to quickly locate connectivity violations.
Supports three flexible flows for building power schemes: Config, DEF, and Hybrid.
Supports multi-task concurrent simulation.
Supports ultra-large-scale designs with billions of instances.
Supports 2.5D/3DIC and chiplet heterogeneous integration.
Supports disturbance analysis of key interconnect structures—TSVs, hybrid bonding, and upper-level signal routing—on cross-die power-delivery quality.

Application Scenarios
Early PDN planning and EMIR risk assessment for ultra-large-scale chips with demanding scaling requirements. For 2.5D/3DIC and Chiplet heterogeneous integration, it addresses disturbance analysis of key interconnect structures—TSVs, hybrid bonding, and upper-level signal routing—on cross-die power-delivery quality.
