HyperLynx DDR

Overview

HyperLynx DDRx Design and Verification

HyperLynx automatically analyzes complete DDR/LPDDR 3/4/5 interfaces for compliance with signal integrity and timing requirements. HyperLynx automates what other tools can do only manually, guiding users step-by-step and adjusting the analysis flow based on the DDR and controller technologies used.

See how HyperLynx accelerates DDRx design. Pre-layout exploration optimizes designs for cost and performance and ensures they meet protocol-specific requirements. Automated, post-layout verification checks all signals for signal quality and timing requirements, ensuring first-pass design success.

Key Features

Powerful, Automated DDRx Simulation

HyperLynx provides a complete flow for DDRx EM modeling & simulation that understands protocol and component-specific requirements. Actual operating design margins are clearly reported in mV and pS, enabling designers to quickly determine if their design will pass or fail and by how much.


Automated Post-layout Verification

Post-layout analysis automatically extracts detailed interconnect models from layout based on the user’s selections of nets to simulate and crosstalk settings. The resulting models are automatically simulated to determine the design’s compliance with protocol and component-specific signal integrity and timing requirements. Automated post-layout verification supports both single and multi-board designs.

Pre-layout Design Exploration

HyperLynx lets designers evaluate alternatives to optimize for cost and performance while ensuring the design meets stringent signal integrity and timing requirements. Designers can assess the relative impacts of trace length, impedance, routing layer, spacing, and relative length, in addition to via design, drive strength, receiver termination and more to determine the right combination for their design.

Unified, Automated Analysis Workflow

HyperLynx provides a single, consistent workflow for pre- and post-layout simulation. Performing the same analysis, the same way, with the same output reporting allows designers to compare post-layout verification results to their pre-layout counterparts to determine if layout rules were followed correctly. Where results differ, HyperLynx “what if” analysis helps designers find and resolve issues quickly.

Comprehensive Design Margin Reporting

HyperLynx provides DDRx signal integrity and timing results in a comprehensive report that can be shared with others. All signal relationships are covered, including data read/write, address and clock/DQS. Design margins are reported in mV and pS, linked to waveforms that show how critical measurements were made. The report includes links to eye diagram displays that can be examined interactively.

HyperLynx reports provide simple pass/fail feedback on performance margins.

Advanced Analysis Support

HyperLynx accurately analyzes high-speed, densely routed DDR designs. Post-layout crosstalk automatically includes aggressors based on user-defined coupling thresholds. Power-Aware analysis integrates 3D EM modeling to include PDN effects like SSN and non-ideal signal return paths. DDR5 analysis supports IBIS-AMI models and accurate models the impact of rise/fall asymmetry on design margins.
