PCB News - PCB simulation analysis solution

As PCB high-speed signal design becomes more and more popular, electronic circuit design is increasingly faced with signal integrity, power integrity, thermal, electromagnetic compatibility and other challenges. The introduction of simulation verification means in the design will greatly improve the efficiency of product development, design correctness, and achieve the fastest product to market. MentorGraphic's HyperLynx software is the industry's most widely used PCB design simulation tool and supports simulation analysis of major EDA software including Cadence and Altium.

HyperLynx includes pre-simulation environment (LineSim), post-simulation environment (BoardSim) and multi-board analysis functions to help designers perform comprehensive simulation analysis on MHz~GHz PCB networks, eliminating design risks and improving the success rate of design. HyperLynx features include:

1. HyperLynx Signal Integrity

HyperLynx SI is divided into pre-simulation and post-simulation, and the frequency covers MHz~GHz.

The pre-simulation can simulate the high-speed signal of schematic diagram before PCB wiring, analyze the transmission effect of signal under the virtual lamination structure and wiring parameters, optimize the PCB lamination structure, wiring impedance and high-speed design rules (line width/line length/spacing, etc.).

After simulation, PCB design files can be imported, laminated structure and physical parameters can be extracted, transmission line characteristic impedance can be calculated, and signal integrity and electromagnetic compatibility can be tested.

Main features:

. Support all kinds of transmission line impedance planning and calculation

. Support reflection/crosstalk/loss/hole effect and EMC analysis

. Serial, parallel and differential matching schemes for high-speed networks are provided by matching wizard

. Support multi-board analysis, reflection, crosstalk and loss analysis of signals transmitted between boards

. Provide DDR/DDRII/USB/SATA/PCIX and other design packages

2.HyperLynx Power Integrity

HyperLynx PI includes pre - and post-simulation power supply integrity analysis, including DC voltage drop analysis, AC decoupling analysis, plane noise analysis and model extraction.

Main features:

. Determine PCB board current density area is too large

. Analyze the distribution impedance of power supply system at different points on the board

. Analysis of different capacitor placement, installation and cascading Settings appear different effects

. Simulation from IC power supply pin, through the hole to the whole board noise

. Create highly accurate through-hole models including bypass and power plane effects

. Support all mainstream PCB design tools

3.HyperLynx DRC (Design Rule check)

HyperLynx DRC is a design rule checking tool that supports verification of complex design rules, such as EMI/EMC, wiring cross-reference plane changes, shielding layer and hole inspection, and quickly locate potential problems on the circuit board to avoid EMI/EMC, SI or PI errors.

4.HyperLynx 3D EM (3D Electromagnetic Field Simulation)

HyperLynx 3D EM is an electromagnetic field simulation optimization tool for 3D structures. It can verify circuit board electromagnetic design, used for PCB board level, packaging, rf circuit (RFIC), microwave circuit (MMIC) and antenna design simulation verification.

Main features:

. Provide microstrip model library, such as transmission line, branch structure, corner, etc

. Support antenna analysis, array antenna analysis, microwave devices, monolithic microwave integrated circuit MMIC, RF integrated circuit RFIC, low temperature ceramic co-fired LTCC, high temperature superconducting HTS and other analysis

5.HyperLynx Analog (Hybrid circuit simulation verification)

HyperLynx Analog provides Analog hybrid circuit simulation analysis to reduce data errors caused by design transfer between different tools. It can reduce the appearance of design problems and effectively improve the reliability of design.

6.HyperLynxThrmal (Board level thermal simulation)

HyperLynx Thermal Is used for PCB level Thermal analysis. It uses temperature curves, gradients and overtemperature diagrams to help designers solve the overheating problems of circuit boards and components more effectively during design
