Problems when simulate the floating point functions Intel FPGA IP

I build simulation for the floating IPs, but with modelsim simulation, the outputs are always zero. I have tried several arithmetic functions, add, sub, accumulate and divide. However, I got the ...

Hi,

Sorry for the delay. I was just back to office. As I understand it, you observe some issue with floating point IPs in Modelsim simulation. To facilitate debugging, would you mind to share with me on the following:

  1. What is the specific Quartus version and IP that you are using?
  2. Mind sharing with me the .ip file of one of the floating point IP that you are using that I can have better understanding on the configuration.
  3. Please share with me a simple test design or simulation example which could replicate your observation. I would like to perform issue replication to see if can spot any anomaly.

Thank you.
