Reading from FIFO

Can anybody explain me what happens in following situation, before I resort to simulation!

 

For example there is a FIFO created with FIFO generator out of Block RAM, whose write width is 8 and read width is 32 and if the total number of bytes written is not dividable by 32, i.e just before the last 32 bits are to be read, there is only 1, 2 or 3 bytes in FIFO!  What would be output from fifo after that last read is issued! By output I mean Data, flags,...

 

 

If anybody knows, please share!

 

 

Thanks!

Re: Reading from FIFO

Please check "Non-symmetric Aspect Ratios" section in the FIFO Generator User Guide, which is one of the files generated by CoreGen.
