Collaboration Diagram of uvm_mem_single_walk_seq

Runs the walking-ones algorithm on the memory given by the mem property, which must be assigned prior to starting this sequence.

If bit-type resource named "NO_REG_TESTS", "NO_MEM_TESTS", or "NO_MEM_WALK_TEST" in the "REG::" namespace matches the full name of the memory, the memory is not tested.

uvm_resource_db#(bit)::set({"REG::",regmodel.blk.mem0.get_full_name()},
                           "NO_MEM_TESTS", 1, this);

The walking ones algorithm is performed for each map in which the memory is defined.

for (k = 0 thru memsize-1)
  write addr=k data=~k
  if (k > 0) {
    read addr=k-1, expect data=~(k-1)
    write addr=k-1 data=k-1
  if (k == last addr)
    read addr=k, expect data=~k
