I am simulating a model in MATLAB SIMULINK. One of the output signals varies between 0 and 1. I want to apply this output to some next block but the condition is that if output is 0 then introduce delay of few milliseconds and if output is 1 then No delay.
How to achieve this.
Hello Tushar Mahalle ,
I think you can use the "on/off delay". It takes a Boolean input and then allows a time delay to be specified (default of 0.01 s). The only caveat is that if the sample time parameter is greater than 0, the delay time must be a multiple of the sample time.
See the following link for more details:

Hello Tushar,
An option would be using a "switch" block. This block allows you to pass through input 1 or input 2 depending whether a certain condition is met or not (in your case the 0/1 condition). One of the inputs would be the signal without delay, the other the signal delayed.
To introduce the delay you can use the digital delay block "z-1". For this block you need to define the samples the signal is delayed by. For exemple: if the integration time step is 1 ms and you want a delay of 3 ms, you will need three sample "z-3".
Best,
GP
To avoid the 0 delay is to implement the matlab design into FPGA implementation, then you can represent the 0 delay as signal out-put.
