ADS simulator speeds eye measurements
-- Test & Measurement World, 3/1/2009 2:00:00 AM
Agilent Technologies has introduced a million-bit-per-minute signal-integrity channel simulator for multigigabit chip-to-chip data-link design. The channel simulator—part of Agilent’s ADS (Advanced Design System) EDA software platform—allows an interactive eye-diagram measurement from channel simulations performed within the ADS signal-integrity design and analysis environment.
The most common applications for the ADS channel simulator are design and verification of the chip-to-chip multigigabit-per-second serial links found in many consumer and enterprise digital products—from laptop computers to data center servers to telecommunication switching centers to Internet routers. The simulator helps signal-integrity engineers take into account physical phenomena such as impedance mismatch, reflections, electromagnetic coupling, crosstalk, and microwave frequency attenuation due to the skin effect and dielectric loss tangent.
The ADS channel simulator allows engineers to perform “what-if” design-space exploration. To aid this workflow, the ADS channel simulator uses impulse-response analysis to automatically extract a linear FIR (finite input response) model from any combination of ADS circuit-level and physical-level components. This results in simulation throughput of more than 1 million bits per minute. Fast eye measurement lets engineers produce the resulting eye measurements—and optimize transmit and receive equalization—in serial links such as PCI Express, USB 3.0, and 10-Gigabit Ethernet.
The channel simulator will be available as part of the ADS 2009 release. It is offered as part of both the legacy E8885 Convolution Simulator and its successor, the W2302 Transient Convolution Element in the ADS.
