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?

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
*//////////////////////////////////////////////////////////
*
* connections: non-inverting input
* | inverting input
* | | positive power supply
* | | | negative power supply
* | | | | output
* | | | | |
* | | | | |
*.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.

Gruß
Helmut
