Hi Mark:
In such case I need a bit more clarification. I will use the following example, let me know if my bit order assumptions are correct.
Lets say the port is [3:0][2:0][1:0] portname;
Example 1:
If the range is not specified then the width of the default value has to be 4x3x2 = 24.
Default value bit ordering, leftmost ---- rightmost
portname[3][2][1], portname[3][2][0], portname[3][1][1], portname[3][1][0] ---- portname[0][0][0]
Example 2:
If the range is specified = [2:1] then the width of the default value has to be 2x3x2 = 6.
Default value bit ordering, leftmost ----
