Cadence Allegro PCB Footprint Generator

Allegro library work is usually a specialist queue: footprint requests wait days while layout stalls. PartSpark turns the wait into about a minute — AI reads the component datasheet and generates the schematic symbol and footprint as a bundle for the Allegro workflow. Import the EDIF symbol into OrCAD; translate the KiCad footprint or rebuild it using the supplied pad table. Every pin and pad dimension is shown for review.

  • EDIF symbol, KiCad footprint, and pad table with Allegro conversion instructions
  • IPC-7351B land-pattern conventions your fab expects
  • Pin-by-pin review table for datasheet verification
  • Refinement loop for corrections without a fresh generation

How to use it

Three steps, start to library.

  1. [01]

    Generate

    Type the manufacturer part number, or attach the datasheet PDF (or a photo of the pinout and package pages) for unusual parts. A generation takes about a minute.

  2. [02]

    Import the symbol

    In OrCAD Capture, use File › Import › EDIF and select the .edn file from the bundle.

  3. [03]

    Build the footprint

    Allegro can’t read other tools’ footprints directly. Translate the included KiCad footprint, or rebuild it with the Package Symbol Wizard from the pad table in the README, which is already flipped to Allegro’s +Y-up convention.

Doing it by hand, or want to know what to check? Step-by-step guides: how to create a kicad symbol from a datasheet; how to turn a package drawing into a kicad footprint; how to check a generated symbol and footprint before fabrication.

Limits to know

What it won’t do for you.

  • The footprint is not a native Allegro .dra/.psm file. Plan a few minutes for conversion.
  • When the datasheet has no recommended land pattern, the footprint falls back to IPC-7351B conventions or KiCad’s standard footprint for the package, and the generator’s notes say so.
  • Slotted (oval) drill holes and non-plated mounting holes aren’t supported yet. Connectors that need them, such as many USB-C receptacles, need those holes added by hand.
  • Free accounts get the symbol and footprint. 3D STEP/WRL models are on paid plans.

The guide to checking a generated symbol and footprint before fabrication shows real cases where these limits mattered.

Example output

Real parts, checked against the datasheet.

These were generated from the part number alone, then every pin and pad was checked against the manufacturer datasheet. Download the files and open them in KiCad yourself.

FAQ

Common questions

Who is this for?
Engineers on Cadence flows who need a footprint now — prototype teams, consultants inheriting Allegro designs, and librarians triaging a request backlog. Generated parts are a reviewed starting point that turns hours of manual entry into a checking task.
How accurate are the footprints?
The AI extracts pad geometry from the package drawing and follows IPC-7351B conventions, then shows you the dimensions and pin map it used. Treat it like a junior librarian: fast, usually right, and always double-checked against the mechanical drawing before release.
