RE: [sv-bc] streaming operator example

I believe the intent is that the slicing begins with the MSB. I will
enter a mantis issue for this.

Subject: [sv-bc] streaming operator example

 

In SV LRM 1800-2005 section no 8.17,

 

I found the following example:

 

"{ << 4 { 6'b11_0101 }} // generates stream 'b0101_11"

 

This, I think, is wrong. 

 

"If a slice size is specified, then the data to be streamed are first
broken up into slices with the specified number of bits, and then the
slices are

streamed in the specified order."

 

However the verse does not mention the order of breaking up, so the
above stream can be broken up as 'b1101_01 (Left->right) or 'b11_0101
(Right->left). Now stream operator can make the result stream either as
'b01_1101 or as 'b0101_11.

 

Why the first one is not chosen here is not clear to me. Can anyone
explain on this?
