Can anyone Please me on how to build a analog to digital and digital to analog converter Model in simulink?

I have use DAC where i have to convert a digital signal to analog signal so that i can add it to AWGN channel....And the output should be again converted back to digital....I can easily guess that I require a DAC an ADC... but there are no separate blocks for them in Simulink... And I am unable to do it in simulink?...Plz help me...
