Hi all,

is it possibile to get the orginal bit array before making the shuffle?


bit [5:0] vector;
vector = 11010;
vector.shuffle();

Is it possibile to revert the shuffle?

Thanks guys

Array odering methods only works on unpacked array . Please refer to LRM section 7.12.2

Hi,

As stated above, shuffle() only applies to unpacked arrays.

In your example code, if you have used the below, you can use shuffle() (which is what I think you meant)

bit vector[5:0];

I don’t think there is a way to reverse the shuffle(). It makes no sense for such a feature as the user can simply duplicate the array before shuffling if he is interested in retaining the original bit array. Duplicating an array isn’t much of a performance hit either.

Good ol’ unshuffle(), it’s very similar to Kryten’s uncrop feature.
