DEFCON in LT-SPICE?

Question

What does DEFCON mean when running a simulation in LT-SPICE? During many simulations, the SPICE engine supposedly goes into DEFCON, and the quality of the results apparently deteriorates.

Is something wrong with my circuit, or is it just that I am pushing LT- SPICE?

Thanks, Mukund

"mukund"  schrieb im Newsbeitrag news:Hello,maybe yes.At least LTspice has had a hard time to simulate your circuit.You should think about a better circcuit structure or more reasonable valuesin your design. Using Nano-Ohms and Tera-ohms in one circuitfor example can lead to trouble. Also some of the vendor's opamp-modelsare a nightmare for every SPICE-simulator.Best regards,Helmut

Depends on which DEFCON level it was...                                                     {:-)                                        ...Jim Thompson-- | James E.Thompson, P.E.                           |    mens     || Analog Innovations, Inc.                         |     et      || Analog/Mixed-Signal ASIC's and Discrete Systems  |    manus    || Phoenix, Arizona  85048    Skype: Contacts Only  |             || Voice:(480)460-2350  Fax: Available upon request |  Brass Rat  || E-mail Icon at  |    1962     |              I love to cook with wine     Sometimes I even put it in the food
