Altera and Cadence recently collaborated and completed correlation work with Allegro PCB SI using IBIS-AMI models for the Altera Stratix® V FPGAs. Customers may now contact Altera and request IBIS-AMI models for the Stratix V that support all data rates from 600 Mbps to 28 Gbps. The state of the art transceivers used in the Altera Stratix V support leading edge backplane protocols that run up to 12.5 Gbps, as well as the emerging standards for optical interfaces that are planned to be specified at up to 28 Gbps.
Cadence went through a rigorous correlation study and was able to show accurate simulation results. Altera now has the IBIS-AMI model kit for Allegro PCB SI ready to deliver to users of Cadence multi-gigabit signal integrity technology. The kit includes the IBIS-AMI model for the TX driver with pre-emphasis and slew rate control as well as the RX input buffer with linear equalization, adaptive dispersion compensation engine (ADCE) and clock and data recovery (CDR).
The integrated design and analysis solution from Cadence allows for channels to be designed for backplanes or large PCBs, and simulated on the fly with no need for translation from the design environment to a special simulation tool. The Cadence Allegro PCB SI solution with the multi-gigabit option supports having the Altera Stratix V IBIS-AMI model pre-assigned to the transceiver pins on the PCB design, making it simple and easy to begin simulating the channels with millions of bits. Changes to the channel can either be made on the PCB design canvas or in a topology exploration tool, Signal Explorer, which allows what-if changes to be incorporated into simulation without modifying the actual design.
“The integration of design and analysis made Cadence’s Allegro PCB SI environment a natural fit for our state-of-the-art IBIS-AMI models for Stratix V FPGA transceivers,” said Salman Jiva, product marketing manager for Altera's high-speed serial transceiver and signal integrity solutions. “The correlation results we see insure our joint customers will get accurate results when using our models in the Allegro PCB SI environment.”
