HyperLynx DDR Simulator
The easiest DDR Simulator for projects from the simplest to the most complex
HyperLynx DDR is an easy-to-use DDR simulator, guided by a wizard-based interface, which provides powerful analysis for PCBs with DDR memory greatly reducing validation and debug cycles.
HyperLynx DDR Simulate with any number of DRAM devices, from single-memory to multiple-memory modules/slots – including low-power variants – and characterizes Signal Integrity (SI) and system-level timing with setup/hold and derating calculations per JEDEC or custom standards.
Why choose HyperLynx DDR Simulator for DDR Simulation and Analysis?
Easy Setup with DDRx Wizard
The simple wizard-based interface makes it easy to set up DDRx simulations allowing you to get information from a choice of IBIS models for controller and memory devices to drive-strength values for read/write cycles, On-Die-Termination (ODT) settings, and byte-lane / strobe / mask assignment. Wizard configurations can be saved and recalled for future use.
HTML-Based Reports
The DDRx Wizard generates a clean, intuitive report at the end of the simulation process, including pass/fail data. Results can be filtered, letting you explore both timing and SI concerns across data read/write cycles, on the address/command bus, or by differential nets. It greatly reduces the setup time required for successful simulations while providing detailed results that can help drive decisions in your design process.
Detailed, Interactive SI Analysis
Batch-mode simulation data created by the DDRx wizard can be saved to disk, so users can examine several nets simultaneously for detailed SI problems offline, using the HyperLynx oscilloscope. Users can interactively place cursors and take notes of overshoot, undershoot or signal timing.
No Siemens EDA tool required
HyperLynx DDRx supports Altium Designer, OrCAD, Allegro, and CADSTAR, as well as Xpedition and PADS Professional. Independently from the tool you use for PCB Design, you will get successful simulations with detailed results that can help drive decisions in your design process.
White Paper
This paper addresses correlation for a PCB Power Delivery Network (PDN) against decoupling simulations performed with HyperLynx PI. We correlate the frequency-domain behavior of a DDR4 1.2V power rail, with the goal of ensuring a maximum target PDN impedance across a specific frequency range. Even though DDR4 is commonly considered a mainstream technology, many engineers are still struggling to implement reliable interfaces that operate at maximum speed.
How the DDR Simulator speeds up your work
The batch mode simulation data created by the DDRx wizard can be saved to disk, allowing you to use a HyperLynx oscilloscope to simultaneously simulate multiple circuits and examine in detail the problems of Signal Integrity in offline mode.
