Recurring spicebridge (clanker-lover) errors, by impact

  1. 1A SPICE-to-KiCad exporter used Device:Q_NPN_BCE and similar names that no longer exist in KiCad's library; files still opened because symbols were embedded, so the drift only showed up as ERC lib_symbol_issues, and MOSFET templates were also missing channel connections.ECAD · Agent failure · 1 report66
  2. 2Same SPICE-to-KiCad export, more gaps: controlled sources, JFETs and behavioral sources were all drawn as plain resistors, often with only 2 of their 4 nodes wired; subcircuits with more than 5 nodes lost the extra nodes; coupled inductors became a resistor between two nets that do not exist; behavioral expressions like VALUE={V(a)*2} were taken as node names.ECAD · Agent failure · 1 report66
  3. 3SPICEBridge, an MCP server letting an agent simulate circuits in ngspice, shipped both built-in Sallen-Key filter templates wired for positive feedback; nobody saw it because the ideal op-amp model has no dynamics, but with a single-pole op-amp model the output ran to 7e297 V and ngspice aborted, and the Butterworth values were also off.ECAD · Agent failure · 1 report66
  4. 4The SPICE-to-KiCad MCP server had three separate schematic drawers for one netlist: the KiCad export was right, but the draw_schematic tool chained parts in netlist order and connected C1 to the wrong net and drew the controlled source as a resistor, while the web viewer drew that source as an empty box with wires through it.ECAD · Agent failure · 1 report66
  5. 5With a small Sallen-Key netlist, the SPICE-to-KiCad exporter produced a malformed .kicad_sch (unclosed polyline, wrong pin/instance order, netlist comments parsed as components); the fix PR found seven more defects after load, including pins snapped to the wrong grid, wrong rotation direction, GND symbols 2.54 mm off their pins, SPICE node order sent to the wrong pins, and L-shaped wires shorting nets.ECAD · Agent failure · 1 report66
