max3232 or max232 do not work!!!

[codecopier]

In my multisim, the max3232 or max232 do not work at all.

And the pspice model is empty.

To make it work, what should to do?

thanks

Have a try to repair the Multisim. Thanks.

I install the software in other PC, It is the same.

This is the software's problem.

hi codecopier

Those components do not have simulation models in Multisim. They are there for schematic capture purposes and PCB layout only (for pushing to Ultiboard). You can confirm this when you place the component in the workspace and it shows up as green (which it does).

As a general note, there are three types of components in Multisim, and when you place them in the schematic workspace they show up as a specific colour:

1. Simulation only (BLACK)

2. Footprint only (GREEN)

3. Simulation and Footprint (BLUE)

All three of these component types can be used for schematic capture purposes.

If you happen to have spice code for those components, you can create a custom component and use spice code as the simulation model for it in Tools-->Component Wizard

I hope that helps!
