Use a unit delay block

Then set the sample time of your pulse generator and the unit delay block to 1e-6

"with a fixed step just by replacing the sample time of a delay block one can get the required delay" as said by u mr.azzi. But in this method the rising edge is delayed correctly but not the falling edge. Any other method can u suggest. or m-file coading? plz
