Switchercad und LM358

Hi Leute, ich habe gerade versucht, das Spice Modell vom LM358 (von National) in Switchercad einzubinden. Ich bin bisher gescheitert: Too many parameters vor subcircuit "lm358" (instance:x§u2)

Was mache ich falsch?

Hier das asy-File: Version 3 SymbolType CELL LINE Normal -8 8 8 16 LINE Normal -8 24 8 16 LINE Normal -8 8 -8 24 LINE Normal -7 12 -5 12 LINE Normal -7 20 -5 20 LINE Normal -6 21 -6 19 LINE Normal 0 8 0 12 LINE Normal 0 24 0 20 LINE Normal 1 11 3 11 LINE Normal 2 10 2 12 LINE Normal 1 21 3 21 WINDOW 0 4 8 Left 0 WINDOW 3 4 24 Left 0 SYMATTR Prefix X SYMATTR SpiceModel Private\lm358.lib SYMATTR Value LM358 SYMATTR Value2 LM358 SYMATTR Description Single supply OPV PIN -8 20 NONE 0 PINATTR PinName In+ PINATTR SpiceOrder 1 PIN -8 12 NONE 0 PINATTR PinName In- PINATTR SpiceOrder 2 PIN 0 8 NONE 0 PINATTR PinName V+ PINATTR SpiceOrder 3 PIN 0 24 NONE 0 PINATTR PinName V- PINATTR SpiceOrder 4 PIN 8 16 NONE 0 PINATTR PinName OUT PINATTR SpiceOrder 5

Hallo Michael, irgendiwe hatte ich dein Posting übersehen. Deshalb die späte Antwort.

Das Symbol ist ok. Dann hast du den LM358.mod File editiert. Dort mußt du nur den Namen in der .subckt-Zeile ändern, da dein Symbol nur LM358 sucht. Ob der File .mod oder .lib heißt ist egal. Hauptsache er heißt so wie es im Symbol steht.

.SUBCKT LM358/NS 1 2 99 50 28

ersetzen durch

*.SUBCKT LM358/NS 1 2 99 50 28 .SUBCKT LM358 1 2 99 50 28

Die Netznamen(nummern) nicht verändern. Das wäre unnötige Arbeit. Es kommt nur auf die Reihenfolger der Namen(Nummern) an. Die Reihenfolge muß gleich sein im Symbol.

*LM358 DUAL OPERATIONAL AMPLIFIER MACRO-MODEL *////////////////////////////////////////////////////////// *

  • | | | | |
*.SUBCKT LM358/NS 1 2 99 50 28 .SUBCKT LM358 1 2 99 50 28 *

Das heißt, im Symbol muß folgende Reihenfolge stehen:

In+ 1 In- 2 V+ 3 V- 4 Vout 5

Das ist bei deinem Symbol der Fall. Damit ist das Symbol in Ordnung.
