IBIS Model Generation

SiSoft has been involved with the IBIS initiative since its beginning and has established itself as a leader in developing and validating quality IBIS models. We are an active member of the IBIS Open Forum and have a strong commitment to open modeling standards.

SiSoft consultants utilize SiSoft's proprietary process, called SiQ, to generate and validate I/O Buffer models to ensure accuracy and quality. SiSoft is typically able to achieve greater than 99 percent correlation between IBIS and HSPICE™ models. SiSoft IBIS modeling process accurately extracts component capacitance and models devices containing on-die termination (ODT) and differential I/O. SiSoft's IBIS models are developed to be portable across IBIS simulation platforms.

IBIS-AMI Modeling Services

IBIS-AMI is a modeling standard for SerDes transceivers created to enable fast, statistically significant analysis of high-speed serial links. IBIS-AMI based analysis enables designers to optimize their serial links for performance, reliability and cost. SiSoft is one of the original authors of the IBIS-AMI standard and continually works with its Semiconductor Partners to extend the standard for new technologies.

IBIS-AMI model development

SiSoft consultants work with you to assess your current modeling methodology and determine the best way to develop and validate IBIS-AMI models. SiSoft's consultants then develop models for your transceivers, providing validated models and correlation data.

IBIS-AMI Training

SiSoft can train your staff on the IBIS-AMI standard and show you how to utilize existing models (Matlab, HSPICE, …) to create and validate a fully compliant IBIS-AMI model. SiSoft can accelerate your model development process by licensing its AMI technology code library, which includes algorithms for modeling transmit equalizers, peaking filters, Decision Feedback Equalizers (DFE) and different clock recovery schemes. SiSoft on-site training covers any licensed source code to ensure your developers will be effective.
