Calculate the capacitance of your high-frequency PCBs with the PCB-Investigator – Convincing advantages over other tools!

Maintain the signal integrity of your high-speed buses such as DDR4, or clock signals with the intuitive and precise Capacity Calculator in PCB-Investigator. This powerful analysis tool helps you detect uneven capacitive coupling to ground early in the design process – before it becomes a costly issue in production.

  • Accurately calculates the capacitance between impedance-controlled traces and their reference ground
  • Detects imbalanced coupling in bus systems – a common cause of signal degradation
  • Uses layout geometry to identify overlapping areas between signals and ground planes
  • Applies the parallel plate capacitor formula to each segment for precise and localized results
  • Visualizes areas where ground referencing is interrupted (e.g., due to via holes or cutouts)

Coupled high-speed nets require consistent capacitance to ground to ensure signal stability. Even minor disruptions, such as a via opening beneath a single bus line, can cause significant differences in capacitance compared to other lines – leading to skew, reflections, or EMI issues.

Benefits at a Glance:

  • Improved signal integrity for high-speed digital designs
  • Early detection of critical layout issues
  • Supports layout optimization during the design phase
  • Easy to use – no external simulation required
  • Trusted analysis results directly within your design environment

Ensure the functional safety of your PCB design – make the Capacity Calculator part of your layout review workflow.
