Signal integrity asks whether an interconnect preserves the intended waveform. Power integrity asks whether the load receives an acceptable supply during the conditions that matter. Both depend on physical current paths.
What to examine in the layout brief
Review reference geometry and transitions for the signal paths, then examine power distribution, decoupling connections and return sharing. Identify places where a placement or plane decision affects both reviews.
What belongs in the release record
Keep the separate acceptance criteria visible in the project brief. A power conductor calculation cannot validate a signal channel, and a correct impedance value cannot establish dynamic rail behavior.
Discuss this with Circuit Edge
Send the current schematic and board revision, mechanical constraints, intended construction and the question you need resolved. Circuit Edge Technologies provides PCB layout, hardware-design support, manufacturing review and practical training from Sector 70, IMT Faridabad. A useful enquiry separates the supplied inputs from decisions that still need agreement, so the scope of the review stays clear.

Numerical limits and acceptance criteria must come from the actual component documentation, supplier agreement and applicable standards. No proprietary standard tables are reproduced.
