For following model I recieve an error
Cannot solve algebraic loop involving 'boo/Subsystem/Bistable6/Model/RESET Priority' because it consists of blocks that cannot be assigned algebraic variables, such as blocks with discrete-valued outputs, blocks with non-double or complex outputs, Stateflow blocks, or nonvirtual subsystems. Consider breaking the algebraic loop. For example, add a delay or a memory block to the loop.
I tried to add delays 1/Z as suggested but I didn't helped me much(bistable is a SR-FF)

So what is the solution? Should I add a delay or memory block and if yes where it should go?

As you are using discrete time, then add a Unit Delay on the Q output -- before it goes to the scope or to the GOTO.

The solution was to add a memory block so now I don't recieve anyerror.
Could someone explain if I had used 1/z delay it would be better?Capture.PNG
