Allegro Sigrity Serial Link Analysis Option

You can start using the Cadence^® Allegro^® Sigrity™ Serial Link Analysis Option at the earliest stages of design, before schematic netlists and physical layouts are available. For example, begin by performing feasibility studies with full die-to-die channel topologies for the serial link of interest using a transmission line editor, a via creation tool, and sample AMI models.

As the design progresses, you can replace pre-layout models with more detailed extracted models in a top-down methodology. When IBIS-AMI models are not available, use a wizard-based approach to choose equalization techniques to create representative models (requires access to C compiler) for use in Cadence tools.

For interconnect modeling, you can use the tool’s accurate field solver engines to create detailed post-layout S-parameter extraction of physical layout, and populate blocks in the schematic simulation environment. If you’d like to accelerate simulation time and enhance convergence, you can convert these S-parameters to SPICE sub-circuits.
