ID:13388 Verilog HDL error at <location>: range index cannot contain X or Z
CAUSE: In a Verilog Design File (.v) at the specified location, you used a Don't Care (X
) or High Impedance (Z
) value in defining a range. However, a range represents a number of bits, so an X
or Z
value is not legal for a range specification.
ACTION: Edit the design so all values in range specifications evaluate to a constant integer.
