Simulation and Analysis
High-Speed Signal Integrity
High-speed designs are increasingly prevalent in hardware systems, presenting the challenge of preserving signal quality across extended distances on printed circuit boards and wire harnesses. Signal integrity simulations are employed to assess the efficacy of measures implemented to uphold signal integrity. Subsequently, verifying signal integrity is essential to confirm compliance with industry standards following the design process prioritizing signal integrity considerations.
Capabilities of signal integrity analysis include:
- Detection of ringing phenomena, encompassing over/undershoots and monotonicity deviations.
- Accurate calculation and selection of termination methods to prevent signal degradation.
- Application of design guidelines and optimization of stack-up configurations to enhance signal integrity.
- Identification and mitigation of signal reflections within interconnects to maintain signal quality.
- Assessment of electromagnetic radiation emitted by traces to ensure compliance with standards and minimize interference.
- Analysis of topology and transmission line characteristics to optimize signal propagation.
- Generation of waveforms, eye diagrams, and routing reports to visualize signal behavior.
- Evaluation of crosstalk between signal traces to prevent interference.
- Analysis of signal losses along transmission lines to optimize signal strength and integrity.
Capabilities in Power Integrity Analysis include:
- Establishment of board design databases for thorough analysis.
- Conducting AC and transient analyses to assess dynamic behavior.
- Single node analysis to strategically place capacitors for optimization.
- DC and steady-state analyses to ensure stable operation.
- Defining target impedance levels to minimize I2R losses.
- Multi-node analysis to fine-tune component placement for overall efficiency.
Power Integrity Analysis
In high-speed designs, Power Integrity is paramount due to increased switching rates. Our expertise in high-speed designs ensures that your system’s Power Integrity remains uncompromised. Through careful circuit design, we mitigate common-impedance coupling and common-mode switching noise, minimizing their impact. This approach not only maintains Power Integrity but also reduces signal integrity issues stemming from power supply fluctuations.
