Capture lets you give one reference designator to two different parts. Allegro's netlister refuses that design. The universal-netlist reader, which feeds an agent query and ERC layer, keyed parts by refdes, so the last pin written won and the part reported a mix of both parts' wiring. Now each part keeps its pins, a pin query on that refdes is refused as ambiguous, and export refuses either case.
Recurring agent failure issue in universal-netlist (IntelligentElectron)
What engineers report
A recurring agent failure problem in universal-netlist (IntelligentElectron) that mostly hits the electrical engineer.
Failure pattern: agent / failure
Analyst note
From the Grok pain-radar digests, Nov 10-11 2026 (Nov 10 8:41 AM ET through Nov 11 7:41 AM ET digests plus the Haitch editions). Verified live 2026-11-11: issue/PR read; title and state confirmed.
What it costs a team
Modeled annual cost
$30,000
For a team of 5
Prototype delay
3 days
Modeled schedule slip per occurrence
Time lost
240 min
Per engineer per month, about 1 incidents
How the cost is modeled
240 min/month × 5 engineers × 12 months = 240 hours × $125/hour = $30,000

More recurring errors in universal-netlist (IntelligentElectron)
- export-json ignores --design_variant: four exports of a two-variant Cadence design (no variant, A, B, and a nonexistent variant name) all exit 0 and are byte-for-byte identical, and the file records no variant, so nobody downstream can tell which build it is. The query tools on the same design refuse to run without a valid variant.ECAD · impact 74
- An Altium project with CR CR LF line endings reported No schematic documents found and silently lost every netlisting option, falling back to defaults.ECAD · impact 66
- Follow-up to #272 from the last sweep: export now refuses a missing or unknown variant and writes metadata.designVariant, so downstream tools can tell which build a file is.ECAD · impact 66
- Old OrCAD .DSN files with Library stream 1.1 or 2.0 failed with Expected null terminator for empty string at offset 358, hitting 14 corpus designs.ECAD · impact 66
- The universal-netlist parser dropped every pin with no number, so nets came out short, and one real part's three GND pins made an agent think a ground pin was floating.ECAD · impact 66
- A netlist plugin for agents failed in the Claude desktop app with Executable not found in $PATH, because GUI-started apps build PATH from a login shell, which reads .zprofile and not the .zshrc line the installer wrote.ECAD · impact 58
