I am trying to change a generic in my testbench when I start the simulation (using Questasim base). I am using the following script :-
TestName tb_test1
analyze tb_test1.vhd +acc
simulate tb_test1 [generic USE_ADV_MODE 1]
I get the following output from the simulator
vopt {*}-work dma_mm2s -L dma_mm2s tb_test1 common.glbl -o tb_test1_opt…[Read more]

I found the issue. The problem was that the reset was undefined right at the start which was causing some issues.

I am using the AXI stream receiver to receive data from a DMA controller. I am using Get to read values from it. The problem I am seeing is that I am reading two words of all zeros before I get any activity on the AXI stream receiver. Once I get data then I can read that fine. But I dont understand why I am getting these two values. I do call Get…[Read more]

Hello Mikkie, sorry for not seeing your question.

To merge results:
vcover merge merged.ucdb run1.ucdb run2.ucdb run3.ucdb

Then the normal “report” to view the combined report:
vcover report merged.ucdb

Note, the VHDL has to be identical otherwise you’re trying to merge results that are not aligned, I think Questa gives an error.

Hello,
I’m new to using the OSVVM libraries,
and I’m trying to use the VC Ethernet model (xMiiMacTransmitter.vhd).
It seems to me there’s an error in the clock generation process (ClkProc).
The tperiod_xClk signal takes a period value calculated according to the configuration (I agree with that),
but the RefGtxClk signal changes state after this…[Read more]
