High speed simulation tool

This type of design software unifies all your tools in a single program. All your features and extensions are present within a single interface with a consistent workflow. The best features for high-speed PCB design are rules-driven.

Signal integrity in PCB design is all about ensuring your traces have required impedance and that losses are minimized. The other important aspect of high-speed PCB routing and signal integrity is proper component placement and layout. Your CAD tools need to help you carefully route traces so that your design constraints are satisfied. The right design and analysis tools can help you identify and solve reflection, losses, and impedance problems due to your routing without manually inspecting every interconnect.

The right set of design tools will let you check your design and apply termination networks, adjust trace lengths, and design your PCB stackup to provide specified impedance in a single platform. Powerful verification and simulation tools should integrate directly with your design rules, streamlining your workflow and improving your productivity.

The features you need are all in one program, and all with an intuitive graphic interface. When working with high-speed PCBs, especially devices with high pin density, it can be difficult to see which sections of your device might be causing problems in your board due to crosstalk, EMI, or improper terminations.

In printed circuit boards, crosstalk occurs in two traces running side by side in the same layer or in adjacent layers. Provided by the Springer Nature SharedIt content-sharing initiative.

Generally, the problem of power integrity is mainly solved in two ways: optimizing the stack design, layout and wiring of circuit boards, and increasing decoupling capacitance.

Placing the appropriate decoupling capacitor in the appropriate position will help to reduce the problem of system power integrity. However, when the system frequency is higher, the effect of decoupling capacitor is very small. Power integrity requires higher skills of engineers and is a new challenge for high-speed design. It involves not only board level, but also chip and package level It is suggested that engineers engaged in the design of high-speed circuit boards should do power integrity after solving the problem of signal integrity.

Simulation is the test of a virtual prototype that takes all aspects into account. As the design becomes more and more complex, engineers cannot implement every scheme. At this time, they can only judge with the help of advanced simulation instead of test.

Designers hope to use advanced simulation tools to find out problems in the design stage, so as to complete the system design with high efficiency and high quality. In the traditional circuit board design, engineers seldom use the means of simulation.

More often, the reference design and design guidelines i. In this way, it will start again and again until the problems are basically solved. Even if simulation tools are occasionally used for design, it is only limited to local circuits. Modifying the circuit means a time delay. This delay is unacceptable under the pressure of rapid product launch.

Especially for large systems, a small modification may need to overturn the whole design and start over again. These factors make it difficult for the above design methods to meet the challenges brought by the increasingly complex high-speed and high-density PCB design, so they must be solved with the help of advanced simulation tools.

Once impedances for reflection and ringing have been baked into the PCB layout, the signal integrity simulator may be set up to analyze high-speed signal behavior. The simulator accepts signal stimulus defined by the designer.

The PCB designer also includes parametric characteristics of the high-speed signal nets such as overshoot and undershoot values, flight times, and supply net limits. The simulator uses these values to display results in the Waveform Analysis window. The resultant waveform shows signal integrity issues such as ringing, reflection, crosstalk, or voltage droop induced on the high-speed lines by characteristics of either the PCB layout or filtering discretes.

The PCB designer is able to adjust impedances to maximum signal integrity and continue to perform waveform analysis until the design is free of noise. Altium Designer is a powerful and easy-to-use Schematic Capture and PCB layout tool that allows impedance setting for high-speed traces while you work.

Using the PCB editor, its unified environment makes it easy to use, getting you to the results you need for signal integrity within your designs before the Printed Circuit Boards go to manufacture.
