Hi Gianico,
Each AxiStreamReceiver needs its own transaction record. In the OSVVM testcases, we are using a single record named StreamRxRec. You need separate ones, such as StreamRx1Rec and StreamRx2Rec.There is an example of this done with the Axi4 interface. See directory OsvvmLibraries/AXI4/Axi4/testbench_MultipleMemory. In there see the…[Read more]

Hello!
I would like to consult this matter.
Currently we are involved in a project where our testbench has 2 AXI4 Stream Receiver VCs. This is due to the DUT has 2 output image streams to be checked.
In the Testcase, there are 2 processes for each instance of AXI4 Stream Receiver VC. The 2 processes are running in parallel. As a result we are…[Read more]

First, you are using the older, protected type based API. You might want to consider using the newer, singleton based API – it is simpler and does not require the test writer to use protected types (they are hidden internal to the singleton).
If you look at the document, OsvvmLibraries/Documentation/CoveragePkg_user_guide.pdf, you will find…[Read more]
