AttributeError when accessing unpacked 2d array (with packed 1d array)

[sumpster]

Hi,
the following minimal test produces the effect.

SV test bench:

module Array_tb;
    logic [9:0] matrix1 [2];
    logic [9:0] matrix2 [2][2];
endmodule

Python test:

@test ()
async def testLoadMatrix(dut):
    print(dir(dut))
    dut.matrix2[0][0].value = 1

Yielding the error:

AttributeError: Array_tb contains no object named matrix2. Did you mean: 'matrix1'?

When I look at the output of print(dir(dut)) matrix1 is contained in dut, but matrix2 is not.
(Removing print does not have any effect, neither does removing matrix1.)

Is this a bug or is there a limitation to the number of supported dimensions?
