112Gb/s PAM4 ADC-based SerDes Model in Simulink and IBIS AMI for IEEE 802.3ck


SeriaLink Systems Ltd announces a behavioral model for a 106Gb/s PAM4 ADC-based SerDes in Simulink and IBIS AMI. In collaboration with MathWorks, SeriaLink Systems is proud to announce a behavioral model of a highspeed ADC-based multi-standard SerDes developed with MATLAB and Simulink, a block diagram environment for simulation and Model-Based Design of multidomain and embedded engineering systems. An automated flow configures the model for a desired communication standard using COM reference transceiver parameters. The configuration flow augments the COM parameters with analog design data when necessary. Using the SerDes Toolbox, the model automatically generates dual IBIS AMI models (statistical and time domain). This enables leveraging the signal integrity (SI) simulation infrastructure to explore the SerDes performance beyond COM capabilities, accounting for time-varying and non-linear effects due to CDR, ADC, and non-linearities in the system.

The implementation in MATLAB and Simulink allows the model refinement with the design data through the project lifecycle. “With data rates reaching 106Gb/s, SerDes designers must rely on ADC-based topologies and PAM4 modulation. This fuels the need to account for non-linear and time-varying effects early in the architectural development phase. Our modeling framework expands the simulation capabilities beyond linear COM analysis while maintaining the model flexibility. Furthermore, exporting the models to IBIS AMI with minimum effort facilitates a more efficient interaction between all participants of the ecosystem: SerDes IP providers, component vendors and system integrators,” says Aleksey Tyshchenko, CEO of SeriaLink Systems. “SerDes designers developed IBIS-AMI models correlated with the silicon results using the SerDes Toolbox, and it took a fraction of the time required by alternative methodologies. Now, thanks to SeriaLink Systems, these designers can also use COM to configure the model and go beyond COM’s limitations,” says Barry Katz, development manager at MathWorks.
