Enfrenté algunos errores al intentar simular un circuito. Intenté simplificarlo, pero los errores se mantuvieron en su lugar: |
El siguiente mensaje de error es lo que recibo:

Estoy usando gEDA gscheme para generar el esquema, haciendo una lista de redes usando gnetlist y spice-sdb backend, intentando simularlo en gSpiceUi.
