Proper way of using floating point core?

Hello everyone,


I am trying to add two 32 bit IEEE 754 standard floating point numbers. The thing is i am using the floating point core for virtex 5 and it works fine in simulation, but simulation does not match what happens on the FPGA chip?



What am i doing wrong? I wait for the core to signal Ready , but it seems it never does come high and at times it gives different results!

If you don't know any techniques for debugging, this is a really good time to learn.

Got anyone close by who can teach you some of the basics?

1. Read the manual or user guide. Have you read the manual? Can you find the manual?
2. Search the forums (and search the web) for similar topics.
3. Do not post the same question on multiple forums.
4. Do not post a new topic or question on someone else's thread, start a new thread!
5. Students: Copying code is not the same as learning to design.
6 "It does not work" is not a question which can be answered. Provide useful details (with webpage, datasheet links, please).
7. You are not charged extra fees for comments in your code.
8. I am not paid for forum posts. If I write a good post, then I have been good for nothing.
