Detailed Description
An implementation of a uvm_packer which returns bitstreams that are ready for md5 packing.
Generates bitstreams which follow the format below, as specified in RFC 1321
| Bits | Information |
|---|---|
| 0 - length of the serialized item-1 | Serialized item |
| length of the serialized item - lentgh of the serialized item+6 | Zeros |
| length of the serialized item+7 | One |
| length of the serialized item+8 - (512*x-64) | Zeros |
| last 64 bits | length of the item modulo 2^64 |
NOTICE: The current implementation of the md5_packer only manipulates the bitstream returned when get_bits or #get_packed_bits is called, and does not modify the underlying bitstream. After calling get_packed_bits or get_bits, call clean to clean the underlying bitstream, allowing the packer to be reused
