Wire assignment in verilog

[Altera_Forum]

Hi All, 

When going through a reference design i encountered a particular type of wire assignment as follows.  data[92-:8]=a;  what does this part[92-:8] mean? is it actually 92:84 ie 92:(92-8)?  Thanks in advance

You have it mostly correct, but it would actually be equivalent to data[92:85]. It means to include 8 bits total starting from data[92] and counting down. [92:84] would be 9 bits instead.
