How can I make a JK Flip-Flop with clear and preset?

I wish to design a jk flip flop with preset and clear in Simulink Matlab. I have trying a few designs... but all of them show faulty waveforms....

In matlab simulink library, Is there no flip flop with preset and clear? Should I design it?

And then...how I make it...? Please help me....I search that for 10 hours, but there is not information about that...

Hello,

J-K Flip Flop is included in Simulink Extras.

You can use it.

I know that...but it isnt include preset, and clear.... I want to know about it.

I think the preset terminals are generally asynchronous, is that correct?

Asynchronous simulation is not possible in Simulink, so I don't think it has that terminal.
