How to input a digital signal in simulink?

Hi, I want to input a digital signal with differing time period. For example say, 110110101110101, something like this. And every '1' or '0' should last for say 2 time cycles. I want to do this in simulink. Can anyone help me know how to and what block to use?

Thanks Ram.

using Signal Builder you can set the signal for different time period

Thank you. We can use a repeating sequence stair.
