The Momentum G2 Element is the improved 2nd generation of the powerful Momentum 3D planar electromagnetic simulator from Keysight EEsof EDA, the technology and innovation leader in high-frequency mixed-signal electronic design automation (EDA). Momemtum G2 is seamlessly integrated into the Advanced Design System (ADS), the only design simulation platform that enables the co-design of IC, package and board in high-frequency and hi-speed applications. It seamlessly integrates system, circuit, full 3D electromagnetic simulation with Keysight’s test instrumentation for you to do single pass successful electronic designs repeatedly.

Momentum G2 is an advanced Method of Moments (MoM) 3D planar electromagnetic simulator, enhanced with the latest NlogN and multi-threading solver algorithms, to deliver the fastest and highest capacity 3D planar EM simulation possible. Integrated within ADS, it allows electromagnetic simulation to be used together with circuit and system co-simulation or co-optimization to account for proximity or radiation effects of planar structures such as traces or printed antennas. Visualization of the results in terms of surface currents or radiated fields provides insights on where to fix problem areas.

Momentum G2 is paired with a ingenious parameterized passive model generation capability called Advanced Model Composer (AMC). AMC enables you to create EM based custom libraries of planar 3D models such as transitions, discontinuities or passive components not available in the standard simulation libraries because of novel geometries or dimensions beyond the range of validity. AMC libraries retain the accuracy of EM simulation but simulate and optimize at the speed of circuit simulation through smart interpolation across the parameterized EM database.

Momentum Turbo further accelerates the simulation of Momentum G2 by over 6x through parallel computing on up to 8 nodes per license of a compute cluster. This is especially useful for large simulations of complex boards or packages for signal integrity applications.

Unlike other planar standalone EM simulators with restrictive rectangular grid meshes or socket-based integration with inconsistent user interfaces, Momentum G2 and Momentum Turbo provide the most efficient and fastest 3D planar EM simulation capability integrated with the industry’s most capable Advanced Design System platform through a common design entry, simulation and optimization user interface. This guarantees you to consistently deliver optimal designs at peak efficiency.
