Totem is the “industry’s first” integrated power and noise integrity platform that addresses the challenges associated with global couplings of power/ground noise, substrate noise, and package/PCB capacitive and inductive noise, for analog, mixed-signal, memory, and high-speed I/O designs. It is a comprehensive platform that incorporates transistor-level noise injection, parasitics extraction, package modeling, dynamic analysis, and design debug in a single-flow environment.
The platform’s key technology is based on the concurrent analysis of noise propagation through the power delivery network, substrate network, and package/PCB parasitics. It accurately analyzes noise coupling effects at every time-point using a single-kernel solver. This advanced technology enables designers to account for all global noise impacts on their designs, a critical challenge for post submicron mixed-signal SoCs.
Totem is a full-chip layout-driven analysis solution integrated with existing analog environments. It provides cross-probing of analysis results with industry standard circuit design tools for efficient debugging, fixing, and optimization. Designers can use Totem for early stage prototyping to guide their power network and package design. In addition, it can be used for chip sign-off and post-silicon debug.
The accuracy of power noise analysis is critical for functionality, timing, and reliability of analog designs. Totem incorporates transistor-level power model with voltage de-rated switching current technique, and SPICE-accurate decoupling capacitance extraction. In addition, impact of package and board effects is included through the support of broadband S-parameter package and PCB models.
It delivers the capacity required for standalone DRAM, Flash, and CMOS image sensors, as well as embedded memory macros. It leverages RedHawk-NX’s mesh pattern recognition (MPR) extraction technology and multi-core simulation engine to handle hundreds of millions of transistor designs overnight. Totem also offers simulation-based electro-migration (EM) validation for power and signal nets. It supports both Root Mean Square (RMS) and Peak current EM checks, which are critical for advanced process nodes, in addition to conventional average current-based methods.
