I need to have a trigger block, which should trigger only one block at a time.

For example

I have 2 blocks A , B connected to the trigger block T, this triggering block T should trigger one of these A, B blocks at different instances. i.e trigger A at instant 0, A at instant 1, B at instant 2, A at instant 2 and so on.

which triggering block should i use?

And should i use any code to have this timed triggering

waiting fr ur valuable response

Thank you

it should fire contiously.. as i am trying to convert a synchronous data flow graph into a synchronous block diagram..!

when A block is triggered should produce some tokens ( 2 for my model) when B block is triggered should consume some tokens ( 3 for my model)

So like this i need to form a producer-consumer model!! the trigger can be in any order.!

But preferably A,A,B,A,B because when A is fired twice (2+2 tokens produced), it is sufficient for B to get 3 tokens from double firing of A, then so on.

Yes the trigger sequence is as expected!! thank you,

And which block did you use for A, B is it triggered subsystem block?

在 MATLAB Online 中打开

Yes it is triggered subsystem with rising edge trigger type.

Initially at t=0, output of unit delay block will be 1 (Initial condition:1). So switch block will send the input-1 to the output which is equal to 1.

Afterward, output of switch block will come from input-3 connected to repeating sequence stair.

Repeating sequence stair will generate the sequence of 0 & 1 continuously.

Sample Time        : 0 1 2 3 4 5 6 ....
Switch Blk Intput-1: 1 1 1 1 1 1 1 ....
Switch Blk Intput-2: 0 1 0 1 0 1 0 ....
Switch Blk output  : 1 1 0 1 0 1 0 ....
NOT Blk output     : 0 0 1 0 1 0 1 ....

Hope now it is clear.
