About

Altium’s PDN Analyzer tool integrates directly with Altium Designer so you can easily troubleshoot and detect issues like insufficient or excessive copper, uncontrolled voltage drops, marginal voltage at critical power pins, copper islands or peninsulas and similar issues that may be present with the power system in your PCB design. PDN refers to the power system on printed circuit boards for active circuits. This system includes all interconnections from the voltage regulator module and the metallization of pads and die on integrated circuits that are used to supply and return power current. IC supply voltage limits must be met across the entire length of the power delivery network. Accurately validating your power budget means considering minimum and maximum device limits, worst-case voltage drops, and combined return-path currents. PDN Analyzer shows you exactly where these problems arise.

About

ZapSketch is a browser-based electrical home-run planning tool for electricians, electrical contractors, and estimators. Users can import a floor-plan PDF, sketch walls on a blank sheet, or work from a quick drawing, then place panels, junction boxes, and devices and route circuits and raceways. The application measures run lengths and provides preliminary conductor-sizing, ampacity, voltage-drop, and conduit-fill feedback as the layout changes, using documented NEC 2023 calculation assumptions. Users can review circuit schedules and export marked-up plan PDFs and raceway pull schedules for estimating, review, and field handoff; some export details and unwatermarked reports require Pro. Free standalone voltage-drop, wire-size, and conduit-fill calculators are also available. ZapSketch is a preliminary planning aid, not a replacement for adopted-code review, engineering judgment, or verification of project conditions.

Pricing

$19/month
Free includes the planning workflow and preliminary checks; PDF exports are watermarked and redact commercial pull and calculation details. Pro is $19 per month, or $190 per year, and adds unwatermarked PDF exports, full raceway pull schedules, complete preliminary calculation reports, and commercial-use output. Standalone voltage-drop, conduit-fill, and wire-size calculators are available without signup.
