Hi I’m trying UVVM 2021-10-22 with questa 2021.3

I’m seeing a compilation error reported in the following file

# \*\* Fatal: (vsim-3714) At array depth 2, array lengths do not match. Left is 6 (7 downto 0). Right is (UNDEFINED) (UNCONSTRAINED ARRAY).

# Time: 602 ns Iteration: 10 Process: /ethernet\_sbi\_gmii\_demo\_tb/i\_test\_harness/i2\_ethernet\_vvc/i\_ethernet\_rx/cmd\_executor File: ../script/../src/vvc\_methods\_pkg.vhd

This points to line 716 on vvc\_methods\_pkg.vhd

v\_packet(8 to 13) := bridge\_to\_hvvc.data\_words(0 to 5);

I’m just executing the compile\_all\_and\_simulate. script from within the bitvis\_vip\_ethernet/script folder  
Any suggestions ?

Hi,  
I have not tested with that version, but will download and have it a go. Do you have any other version you can test with?
