Hello all, I don't know if I find a bug or not.
I'm simulating a circuit with a transistor. When I change the value of power supply I get a "open circuit:internal node". The circuit runs well on ngspice, I don't know about what I doing bad. I paste console output: ----------- console cut ------------- cat Sim-2.ckt |grep -iv ^* TRANSISTOR CIRCUITO TRANSISTOR CON CARGA RESISTIVA VCC 1 0 10 VE 4 0 PULSE(0 8 0 0 0 0.5M 1M) Rc 1 2 1K Rb 4 3 8200 Q1 2 3 0 Q2N3055 .model Q2N3055 NPN (Is=974.4f Xti=3 Eg=1.11 Vaf=50 Bf=99.49 Ne=1.941 + Ise=902.5p Ikf=4.029 Xtb=1.5 Br=2.949 Nc=2 Isc=0 Ikr=0 Rc=.1 + Cjc=276p Vjc=.75 Mjc=.3333 Fc=.5 Cje=569.1p Vje=.75 Mje=.3333 + Tr=971.7n Tf=39.11n Itf=20 Vtf=10 Xtf=2 Rb=.1) .print tran V(3) V(4) V(2) I(Rb) I(Rc) .tran 1u 3m 0 >salida.simu2.tran.dat .print dc V(3) V(4) V(2) I(Rb) I(Rc) .DC VE 0 8 0.01 >salida.simu2.cc.dat .END [EMAIL PROTECTED]:~/Practicas_2006/Practica_1/Circuitos/Gnucap$ gnucap -b Sim-2.ckt Gnucap 0.35 The Gnu Circuit Analysis Package Never trust any version less than 1.0 Copyright 1982-2006, Albert Davis Gnucap comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions according to the GNU General Public License.
