Hi Hassan,
The 2024.07 release will have a limited set of predefined events added to OSVVM. One of them will signal that the test case has initialized the VC and the VC can start handler type operation.

I have an initial proof of concept test case working at this point and expect to release it to the Dev branch sometime soon.

In addition,…[Read more]

I believe that the GetAxiStreamOptions could just be used with DEFAULT_ID, DEFAULT_DEST, DEFAULT_USER. However, I am not sure why this is not done anywhere in any testbench that comes with OSVVM.

4. The AXI stream receiver gets the ID, DEST and USER from the transmitter VC. When it gets the data, we can access what the transmitter sent it. What then is the meaning of SetAxiStreamOptions for the receiver? It should only have GetAxiStreamOptions just like it has Get and no Send command. It is a receiver after all.

The USER can be assigned as follows:
SetAxiStreamOptions(StreamTxRec, DEFAULT_USER, User);

Or, within the send and sendburst commands:
Send(StreamTxRec, X”AAAA_AAAA”, ID1 & DEST1 & USER1 & ‘0’, TRUE) ;
SendBurst(StreamTxRec, 8, ID2 & DEST2 & USER2 & ‘1’) ;

The check can be done like this:
Check(StreamRxRec, X”BBBB_BBBB”, ID1 & DEST1 & USER1 &…[Read more]

> What is the meaning of writing something like this: GenBin(2,10,2)

If this is the only GenBin for a given coverage model, this does not change anything.

Note the coverage model that I edited into the previous discussion for the AxiStreamTransmitter. If I instead did:
AddBins (BurstCov.BurstDelayCov, 80, GenBin(2,8,2)) ; -- 80% Small…[Read more]

What is the meaning of writing something like this: GenBin(2,10,2) where the number of bins is more than one, as far as the DelayCoverage Model is concerned?

> Q1. When the GenBin has 3 numbers, why does it always end with 1? This means that we are creating a single bin that has the specified range? This means that any integer can occur in that range with equal probability?

The third parameter indicates how many bins to split a range into. As you observed, this puts it all in one bin. It is indeed…[Read more]

There was. It was removed as it did not work in one of the vendors. I will need to add it back.

I guess converting it into record is the correct way forward in that case, since that is how it works with the memory mapped AXI4 VC.

So is there any example that uses the AxiStreamGenericSignalsPkg at the moment?
