Inverted clock for flipFlop in dsp builder

Hi,

I am implementing a MAxPlus project in DSp-Builder.

2) In one part of circuit the clock input of the FlipFlop is inverted using an inverter. how I can implement this in DSP-builder?

3) If i try to use HDL import it gives error of Multiple clock due to same above reason. Any idea how to fix this issue?

kind Regards
