Netlist round trips dropped SPICE expressions and parameters, including a flat deck's .param lost on import.
Recurring agent failure issue in analog-canvas (cascode-ai)
What engineers report
A recurring agent failure problem in analog-canvas (cascode-ai) that mostly hits the electrical engineer.
Failure pattern: agent / failure
Analyst note
From the Grok pain-radar digests, Nov 7-8 2026 (Nov 7 8:41 PM ET through Nov 8 7:41 AM ET digests plus the Haitch overnight edition). Verified live 2026-11-08: 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

Evidence
More recurring errors in analog-canvas (cascode-ai)
- On Spectre import a library block called without its body came back as a generic subcircuit with pins P1 to Pn, landing a DAC's wires on the wrong nets, and on export the DAC contract names VIN and VOUT while the artwork uses IN and OUT.ECAD · impact 74
- A gate whose cell draws its own ground came back from import as a plain block and lost its label, because the import stripped a pin from every caller too early.ECAD · impact 66
- A netlist round trip dropped a source's unprinted waveform settings and an op-amp's rail values because the SPICE card does not print them.ECAD · impact 66
- A part the author never named came back from a netlist round trip named X1 with an extra record for its printed card.ECAD · impact 66
- A schematic editor's part colours did not survive a round trip through its netlist format because the format could not carry a style; background paint still is not exported.ECAD · impact 66
- After a round trip through the RNL format, diodes pointed at an undefined DIODE model and ngspice stopped, because the editor's own exported stand-in card was mistaken for the author's model and suppressed itself; NMOS/PMOS and NPN/PNP had the same bug.ECAD · impact 66
