Please log in for more thread options I'm having more than a problem creating this device, LM317, in CircuitMaker. When I load the "lm317.net" file into CM, I get this message: "No Spice Analysis Specified in: lm317.net". OK, so I pull up the spice data help screen and now I'm totally confused. I gathered that the " % " sign preceeds the designations but, how do I define it as a device? This is my first attempt at creating a device from a netlist so any guidance in this matter will go a long way in restoring my battered ego;-) I've included the LM317 Netlist for examination: *Netlist *LM317 TI voltage regulator - pin order: In, Adj, Out *TI adjustable voltage regulator pkg:TO-3 ..SUBCKT LM317 1 2 3 J1 1 3 4 JN Q2 5 5 6 QPL .1 Q3 5 8 9 QNL .2 Q4 8 5 7 QPL .1 Q5 81 8 3 QNL .2 Q6 3 81 10 QPL .2 Q7 12 81 13 QNL .2 Q8 10 5 11 QPL .2 Q9 14 12 10 QPL .2 Q10 16 5 17 QPL .2 Q11 16 14 15 QNL .2 Q12 3 20 16 QPL .2 Q13 1 19 20 QNL .2 Q14 19 5 18 QPL .2 Q15 3 21 19 QPL .2 Q16 21 22 16 QPL .2 Q17 21 3 24 QNL .2 Q18 22 22 16 QPL .2 Q19 22 3 241 QNL 2 Q20 3 25 16 QPL .2 Q21 25 26 3 QNL .2 Q22A 35 35 1 QPL 2 Q22B 16 35 1 QPL 2 Q23 35 16 30 QNL 2 Q24A 27 40 29 QNL .2 Q24B 27 40 28 QNL .2 Q25 1 31 41 QNL 5 Q26 1 41 32 QNL 50 D1 3 4 DZ D2 33 1 DZ D3 29 34 DZ R1 1 6 310 R2 1 7 310 R3 1 11 190 R4 1 17 82 R5 1 18 5.6K R6 4 8 100K R7 8 81 130 R8 10 12 12.4K R9 9 3 180 R10 13 3 4.1K R11 14 3 5.8K R12 15 3 72 R13 20 3 5.1K R14 2 24 12K R15 24 241 2.4K R16 16 25 6.7K R17 16 40 12K R18 30 41 130 R19 16 31 370 R20 26 27 13K R21 27 40 400 R22 3 41 160 R23 33 34 18K R24 28 29 160 R25 28 32 3 R26 32 3 .1 C1 21 3 30PF C2 21 2 30PF C3 25 26 5PF CBS1 5 3 2PF CBS2 35 3 1PF CBS3 22 3 1PF ..MODEL JN NJF(BETA=1E-4 VTO=-7) ..MODEL DZ D(BV=6.3) ..MODEL QNL NPN(EG=1.22 BF=80 RB=100 CCS=1.5PF TF=.3NS TR=6NS CJE=2PF CJC=1PF VAF=100) ..MODEL QPL PNP(BF=40 RB=20 TF=.6NS TR=10NS CJE=1.5PF CJC=1PF VAF=50) ..ENDS LM317 Randy | ||||||||||||||||||||||||||||||||||||||||

Please log in for more thread options Randy: for an example, look in C:CM06ModelsMCEREGS.LIB There is already an LM317 which looks identical to the one you are trying to create. -- Regards, Robert Monsen "Your Highness, I have no need of this hypothesis." - Pierre Laplace (1749-1827), to Napoleon, on why his works on celestial mechanics make no mention of God. | ||||||||||||||||||||||||||||||||||||||||

You are obviously loading in what CM thinks is a complete spice netlist that has a full run specified in it. You need to look at the documentation to find out how to add an actual *model*. Your problem is that you don't yet know what is what in spice. A spice netlist tells spice how the circuit is constructed and what to do with it. A model is a only *part* of a final netlist. The convention for files with models are .lib, .mod, .sub. The conventions for spice netlists are .cir and .net. If it were SuperSpice, it would be a no-brainier. Just drag drop a model.lib to the main window. The model will show up in the docked list on the left. When you place it is will pop up a dialog allowing you to chose an existing symbol to attach to it, if it cant figure it out itself.

IIRC, CircuitMaker already has LM317 symbol/model. Otherwise, you must create a 'macro' element that refers to your model. Don't ask me how to do this -- I'm no more a CircuitMaker user.

I'm not clear what you are trying to do. Is this possibly a learning exercise, trying to create a model from scratch, but deliberately choosing a model that already exists so that you can check the result? You don't say which version, but from your other thread I assume you're using CM 6. As Robert has said, the CM 6 library already contains an LM317, and it has the spec you have listed. But, as already pointed out, that is the 'model subcircuit data', not the 'netlist'. -- Terry Pinnell Hobbyist, West Sussex, UK | ||||||||||||||||||||||||||||||||||||||||
