TLM analysis fifo .used() and .size()

UVM
1

Hi,

I a bit confused on the purpose of .used() method in uvm tlm analysis fifo. What is the difference between .size() and .used(). When to use what?
I am using the .size() to find the number of elements left in the queue. Is this correct?

Any help would be greatly appreciated.

Thanks,
Madhu

No this is not correct. size() returns you the size of the tlm_analysis_fifo
used() returns you the number of data entries you have in this fifo.

How is this fifo different from regular fifo. I have used .size() to find out the elements left.

This is not correct. the uvm_tlm_fifo has also the function size(), which returns the capacity of the fifo and and not how many places are used.
