Unable to make the IR2117 work for a converter.

I am developing a ZETA converter in the InfineonSpiceDE and to switch the MOSFET I was trying to use the IR2117.
But the circuit seems to not work.
Would really appreciate some help regarding this issue.

What is the sim duration?
Your trace only goes to 57milliSec, but your switching period T is 100milliSec (which seems extremely slow).
BTW, you are aware that 'm' denotes milli, not micro?

No, actually I gave a zoomed in ss of the waveform to show the output of the driver.
I then changed the T to 100n.
But, is it really a time related problem?
Iike I am getting a pulse in the IN pin of the driver. But in the HO pin, shouldn't I get a similar pulse for driving the MOSFET?
