pass value from system verilog to VHDL (std_logic_vector)

[sundar]

Hi,
In my VHDL DUT I have a generic declared as std_logic_vector as below
generic_name : std_logic_vector := "0100000000";

My verification environment is in System Verilog where I need to pass
a value to this generic during mapping it in System Verilog

dut
#(
..generic_name (),
)
....
I cudnt able to pass any value from my test bench and my Questasim
6.3c simulator states
# ** Error: (vsim-3051) VHDL generic 'generic_name' is the wrong type
for the associated Verilog parameter.

Please let me know your thoughts.

Thanks,
Sundar
Note: I had a workaround by leaving the dut mapping as blank and
passing value during vsim like
-g/tb/dut_0/generic_name=10'b0100000000.

See section "VHDL Instantiation Criteria Within Verilog" in the Questa
User Guide. std_logic_vector is not among the supported types for
generics.

Hello Marcus,

I decalred parameter inteeger type and passed it to VHDL wrapper to
convert it into std_logic_vector which helped me in this regard.

Thanks,
Sundar
