Ensuring robust signal integrity (SI) and power integrity (PI) is critical to the performance and reliability of modern electronic systems.
At Designee, we leverage advanced simulation and analysis tools to maintain signal quality in both time and frequency domains, minimize voltage ripple, and meet target impedance across the power delivery network.
Our Approach
Signal Integrity – Time Domain
We analyze time-domain behavior using tools like eye diagrams and time-based waveform to detect reflections, jitter, and signal degradation, ensuring clean signal transitions and timing margins.
Signal Integrity – Frequency Domain
Frequency-domain analysis focuses on insertion loss, return loss, and impedance profiles across high-speed paths. Insertion loss reflects signal power loss through traces and connectors, impacting overall signal quality.
Power Integrity – DC Analysis
We evaluate voltage (IR) drops and current density, across power planes and traces to ensure uniform voltage delivery, proper grounding, and optimal thermal distribution.
Power Integrity – AC Analysis
AC simulations assess the power delivery network’s (PDN) impedance profile and decoupling strategy across frequencies. This ensures low noise, minimal ripple, and stability during transient events like switching or load changes.
Key Benefits
Our signal and power integrity (SI/PI) services deliver improved system performance through enhanced signal quality and stable power delivery, even in high-speed and high-power environments. By identifying potential issues early through advanced simulations, we reduce the risk of design failures and costly rework. This proactive approach shortens development cycles and accelerates time-to-market. Our solutions are designed to meet industry standards for EMI/EMC, jitter, and voltage ripple, ensuring compliance
