From the Scripts_user_guide.pdf:
To run OSVVM scripts in XSIM, start Vivado and then run the StartXSIM using:
source <path-to-OsvvmLibraries>/OsvvmLibraries/Scripts/StartXSIM.tcl

This will then set the simulator to XSIM and instead of analyzing MemoryGenericPkg.vhd, it will do:
analyze deprecated/MemoryGenericPkg_xilinx.vhd

These above write bin values were not generated by the code you posted. See annotations in the code.

I tried printing the logs with writebin. The coverage seems to work. its onyl the YAML reports which does not print it right I suppose:
%% WriteBin: RxCov
%% count PASSED Bin:(1) Count = 1 AtLeast = 1
%% count PASSED Bin:(2) Count = 1 AtLeast = 1
%% count PASSED Bin:(3) Count = 1 AtLeast = 1
%% count PASSED Bin:(4) Count = 1…[Read more]

Hi ALex,
I added the two suggestions I made previously to the code. Choose one of them.
I also changed the WaitForClock(clk, 2) to WaitForClock(InterruptRec, 2).
Usually I do not put clock in TestCtrl. The reason being is if you have lots of
different clocks in your system, it is easy to use the wrong one.

Still does not work which I had already tried. strange that the coverage is always zero. seems to be a structural issue but could not explain why. Starting a new thread for this.

Hi Alex,
I see a delta cycle issue. Call ICover using Cnt rather than rx_cnt_s.
Or alternately do a wait for 0 ns ; before the call to ICover.

Best Reegards,
Jim

Hi Alex,
Please use a separate topic for separate issues.

I don’t see anything obvious in your code. Have you tried single step?

Thanks Jim. Meanwhile I am exploring functional coverage. But cannot get a simple coverage running. Please point out what is wrong here:
rx_cnt_s counts upto 20 which has been verified.
RxCov is a signal.

rx_process : process is
variable cnt : integer := 0;

variable rd_data : std_logic_vector(31 downto 0) := (others =>…[Read more]
