Hurdle the Gigabit-Per-Second Barrier EEsof EDA

Increasing consumer and business demand for digital entertainment and information transmission is driving the need for high-speed systems such as routers, servers, mass storage systems, and PCs. These products include high-speed serial links such as: 

• PCI Express® 
• DDR 
• Display Port 
• S-ATA – XAUI 

At multi-gigabit-per-second data rates and with channel light times longer than a bit period, signal integrity is a major concern. Under these conditions, highspeed analog effects, previously only seen in high-frequency RF and microwave engineering, can impair the signal quality and degrade the link bit error rate. Today’s signal integrity designers are discovering the power of the Keysight Technologies, Inc. Advanced Design System (ADS), which has been the industry standard RF EDA tool for over two decades. ADS provides complete serial link analysis for IC, package, and high-speed board designs.

Bundles

Bundles are pre-configured combinations of software targeted to a specific design workflow. Bundles for signal integrity include the following. 

ADS core, transient convolution bundled (W2210). This bundle provides time domain circuit analysis of high-speed digital channels. Using channel simulator and eye probe, eye diagram measurements can be performed on any ADS circuit. IBIS I/O models, broadband SPICE model generator, and jitter and BER simulation capabilities are included.

ADS core, transient convolution, layout, Momentum G2 bundled (W2211). In addition to the capabilities listed above, this bundle includes layout, full-wave EM analysis of multi-layer planar structures, and popular layout translators. 

ADS core, transient convolution, layout, Momentum G2, EMDS, Ptolemy bundled (W2212). In addition to the capabilities listed above, this bundle includes initeelement- based fullwave 3D electromagnetic simulation, a timed data low simulator for digital signal processing, and Stateye-based BER simulation.

Elements Elements bring additional capabilities to ADS core (W2200) or to bundles, allowing designers and enterprises to customize the configuration of ADS to suit their design needs. In addition to the elements in the bundles above, signal integrity engineers will benefit from the capabilities of the following elements.

Momentum turbo element (E8948). Accelerate large Momentum G2 simulations of complex boards or packages by over 6x via parallel computing.

Electromagnetic professional design system (EMPro) (W2101L). Perform EM simulation using the inite difference timedomain method.

 Verilog-A element (W2303). Simulate Verilog-A models in ADS. This compilerbased solution results in simulation times comparable to built-in models.

Verilog-AMS element (W2304). Simulate end-to-end system behavior with analog and digital components by co-simulation with ModelSim from Mentor or NC-Sim from Cadence.

 ADS transient convolution GT (W2500). Accelerate ADS transient convolution on NVIDIA GPU-enabled computers.
