Siemens mPower 2025.4 is a specialized, high-capacity software tool dedicated to analyzing and optimizing the Power Delivery Network (PDN) of complex printed circuit boards (PCBs) and integrated circuits (ICs). In modern electronics, where low-voltage, high-current demands are the norm, ensuring clean and stable power is critical for reliability and performance. mPower provides engineers with the ability to perform exhaustive DC and AC analyses to identify voltage drop (IR drop) hotspots, optimize decoupling capacitor placement, and validate current density in planes and vios before manufacturing, preventing costly board failures and respins.

Core Functional Capabilities of Siemens mPower 2025.4

• High-Capacity DC IR Drop Analysis
  Simulate the static voltage drop across the entire power network. mPower quickly identifies areas where supply voltage may fall below the required threshold for chips due to resistance in PCB planes, traces, and vios, which is essential for preventing logic errors and ensuring device functionality.

• AC Decoupling Analysis & Optimization
  Analyze the dynamic behavior of the PDN. This feature helps engineers evaluate the effectiveness of their decoupling capacitor strategy across a frequency range, ensuring that transient current demands from switching chips are met without causing excessive power supply noise that can lead to signal integrity issues.

• Detailed Current Density & Via Analysis
  Visualize and quantify current flow through power and ground planes, as well as individual vios. This capability is crucial for identifying potential electromigration risks and thermal hotspots, allowing designers to add vios or widen traces to prevent long-term reliability failures.

• Seamless Integration with PCB Design Flows
  Works directly with native design data from Siemens' Xpedition® PCB layout suite and other major EDA systems. This integration allows for analysis early in the layout process and after placement/routing, enabling a "correct-by-construction" methodology that saves significant time compared to post-layout verification alone.
