What I am doing wrong ? here comes the netlist, the MOD for TLC555 (from ti site). I'm using spice 3f5 under linux. thanks for youe help. * titre .INCLUDE /spice_models/ti/TLC555.MOD X1 0 2 4 1 0 2 3 1 TLC555 R1 1 3 10k R2 3 2 100k C1 0 2 0.1m R4 1 4 1k V1 1 0 dc 15 .op .tran 0.01ms 1s .END TCL555.MOD ****************************************************************************** * TLC555 TIMER MACROMODEL **************************************************** ****************************************4/1/92*****************************DBB * REV N/A ******************************************************************** ****************************************************************************** * COMMON * | TRIGGER * | | OUTPUT * | | | RESET * | | | | CONTROL * | | | | | THRESHOLD * | | | | | | DISCHARGE * | | | | | | | VDD * | | | | | | | | .SUBCKT TLC555 1 2 3 4 5 6 7 8 EREF 15 1 (8,1) .5 GSOURCE 8 3 (8,26) 12.5E-3 GSINK 3 1 (26,1) 67E-3 VD1 8 27 DC .8 VD2 28 1 DC .85 VREF 30 1 DC 1.2 C1 29 1 700E-15 RREF2 30 1 100E3 RREF 15 1 100E3 ROUT 3 1 100K R1 6 1 500E9 R2 2 1 500E9 R3 8 5 75E3 R4 5 9 75E3 R5 9 1 75E3 R6 10 11 1E3 R7 13 14 1E3 R8 8 12 150E3 R9 4 8 500E9 R10 20 19 1E3 R11 16 17 1E3 R12 8 18 150E3 R13 8 21 150E3 R14 22 23 1E3 R15 8 26 150E3 R16 24 25 1E3 R19 7 1 500E9 R20 29 26 1E6 D1 1 11 DMOD D2 12 11 DMOD D3 12 14 DMOD D4 1 14 DMOD D5 18 17 DMOD D6 1 17 DMOD D7 18 19 DMOD D8 1 19 DMOD D9 21 14 DMOD D10 21 25 DMOD D11 1 23 DMOD D12 18 23 DMOD D13 26 25 DMOD D14 1 25 DMOD1 D15 3 27 DMOD D16 28 3 DMOD E1 10 1 (6,5) 1000 E2 13 1 (2,9) 1000 E3 16 1 (15,12) 1000 E4 22 1 (15,21) 1000 E5 24 1 (15,18) 1000 E7 20 1 (4,30) 1000 M1 7 29 1 1 MOSMOD .MODEL MOSMOD NMOS (LEVEL=1 KP=1 VTO=1 RD=5) .MODEL DMOD D (RS=1E-6) .MODEL DMOD1 D (RS=1E-6 IS=1E-9) .ENDS |
