Multiplexer pspice model

Thanks Harry, maybe I need to use a newer version to recognize it. I found a ADG406B could work.

Hey Harry,

I continued to dig on this question and found it might be a dependency issue or missing subcircuit problem for the single files. Look at this post:

pspice error(Subcircuit LOWONSWITCH used by X_U8.X1 is undefined) - PCB Design - Cadence Technology Forums - Cadence Com…

And I found on the ADG1211 file it's like this:

****************

* Logic Low On Switch

*

* Connections

*      101 = S

*      102 = D

*      103 = VIN

*      104 = VDD

*      105 = GND

*      106 = VSS

*****************

.SUBCKT LOWONSWITCH  101 102 103 104 105 106

x1 103 104 105 107 NOTGATE

X2 107 108 104 106 105 VSENSE

X3 108 105 109 ENABLEDELAY

X4 101 102 109 104 105 106 SWITCH

*MODELS USED

.ENDS

while in these files, only the comment are preserved as below. No .subckt are included.

****************

* Logic High On Switch

*

* Connections

*      101 = S

*      102 = D

*      103 = VIN

*      104 = VDD

*      105 = GND

*****************

And the ADG1211 has the definition of LOWONSWITCH, while I still didn't find the prototype of HIGHONSWITCH subcircuit.

Hi Harry,

For some mysterious reason, those file could not be properly load into the pspice as whole file, but I can read them with wordpad.

I'm wondering it's a character issue.

I found the solution, ADG1213 has all the subcircuit these files need. The way to import the .cir file to the cadance capture is using the model editor. This editor could only load one subcircuit into the library. The way to fix this problem is to rename the corresponding .cir file (which in this case, the ADG1213 has all the definition these files need) to .lib and include it in the working library. Then it will work
