FIR II MegaCore strange output

Hi,

I generated a FIR Megacore from the IP catalog, and ran the generated simulation script to check its functionality.

Here is what I got:

Well, it looks very similar to the impulse response, but I noticed breaks between samples...

when I changed back to binary representation I got this:

There are zeros in-between samples!

Can you explain this whether it is normal behavior or wrong usage (bearing in mind that I didn't change anything... it's the original script and testbench)
