RE: [sv-ec] Reversed unpaced array slice

Thanks,
Using streaming operators is a good idea,but don't You think that LRM should
permint such operation on unpacked array because unpacke dmemory
representation. Using in reversed order fragment of nonreversed (packed)
memorywords shoudl be usefull.

No.

I am not sure whether this is explicitly stated, though.

However 11.5.1 says with respect to packed arrays,

A non-indexed part-select is given with the following syntax:

vect[msb_expr:lsb_expr]

Both msb_expr and lsb_expr shall be constant integer expressions. Each of
these expressions shall be evaluated in a self-determined context. The first
expression shall address a more significant bit than the second expression.

11.4.14.2 shows how the order can be reversed using the streaming operators.

Subject: [sv-ec] Reversed unpaced array slice

Hi, I have a question about unpacked array slices:

example code:

bit b [7:0];

initial $display(b[0:3]);

Can I use reversed array slice (or whole reversed array b[0:7] ) ?

I didn not found any explicity example or paragraph in LRM.

Thanks in advance,

Radek
