I utilize your IP fpadd_pipeline with Quartus2- Altera. But it doesn't wotk well. I think fpadd_normalize_struct .vhd has a bug at the line 94 "IF (signed(count) > signed(EXP_in)) THEN".
I think "singed" before "(count)" and "(Exp_in)" is not necessary.
How do you think?

Ashwini, I think you posted in the wrong place.

there is currently a bug related to the normalized numbers. It does work better with the previous version, I hope to have time in the next two weeks to finally close that issue (has been hanging for some time now...).

Granted, signed does not seems to be needed at this point. It will certainly assume the wrong sign from the count for some values, and when sign extending will return the wrong value. Will check it further. Thanks!

IF (signed(count) > signed(EXP_in)) THEN

should be replaced with:
IF ((count) > (EXP_in)) THEN
