modeling an op-amp in matlab simulink simpowersystems

Hi,

I want to model an op-amp in simpower systems but I can't seem to make it work. I've read from one forum to use an adder and connect it to a gain block then using s-ps converter, but still simulink won't let me connect the s-ps block to the simpower block.

You can check out the screenshot below:


I know this is very simple but I really have no idea. Please help.
I have tried using simscape instead since that system has an op-amp block but the simulation is extremely slow and the output is not what I expected it to be. So my options are either

1. to model an op-amp in simpowersystems, or
2. use the op-amp or other blocks in simelectronics and interface it in simpowersystems.

I have no idea how to go about with either of the two options, any help would be highly appreciated. Thank you very much!

hi,
Did you get the solution for this problem???
Is there any way to connect simelectronics components with other DSP tool components.??
