Define Coverage Bin in System Verilog using Incremental Values

I am trying to define coverage using systemverilog for a large coverage area. For example, I would like to define a coverage bin that starts at 24'h000000, ends at 24'h001ff0, and increments by 24'h000008. I have tried this so far; however, it does not compile.

bins scratchpad = {24'h000000:24'h000008:24'h001ff0};

This gives a syntax error: syntax error: token is ':'.

Is there a way to avoid having to explicitly write out all the coverage points? I know that I can define a bin with {24'h000000:24'h001ff0}, but this contains points that I do not wish to include.

You can add a with clause

bins scratchpad[] = {[24'h000000:24'h001ff0]} with (item % 8 == 0);

See http://go.mentor.com/ready-for-systemverilog-2012 for other options and the IEEE 1800-2012 LRM section 19.5.1.1
