MATLAB: Flip-Flop simulation

flip-flopsimulink

Hello, I am begginer in using simulink and I want that to simulate how a D flip-flop works. The question is how can i make a variable boolean value for the D-input of flip flop, i tried to use a constant and make it boolean but she stays only in 1 or 0 no switched value.

If you just want to switch the boolean value, you can do it with the ManualSwitch block. You can double-click the Manual Switch while running the simulation to switch the values.

However, it is not possible to create complex simulation patterns this way, so I recommend using the FromWorkSpace and Signal Generator blocks.

If your question is "how to eliminate an algebraic loop if the Unit Delay changes my system's dynamics", this blog entry discusses reconsidering unphysical algebraic loops in your model. Simscape can be a workaround for loops, see Guy Rouleau's answer on this topic. If your time sampling is continuous you may want to try the Memory block instead of the Unit Delay block which is more appropriate for discrete sampling.
