//   12. Hierarchical structures
//     12.4 Generate constructs
//       12.4.3 External names for unnamed generate blocks
//         Each generate construct in a given scope is assigned a number. The number will be 1 for
//         the construct that appears textually first in that scope and will increase by 1 for each
//         subsequent generate construct in that scope. All unnamed generate blocks will be given
//         the name “genblk<n>” where <n> is the number assigned to its enclosing generate
//         construct. If such a name would conflict with an explicitly declared name, then
//         leading zeroes are added in front of the number until the name does not conflict.
