如何正确的使用checkcifVRF? (instruction from prof. Tony)

1) add VRF in cif file after the data block.

2) Once you have done that, run the CIF 
through checkCIF again and you will see theexplanation(s) automatically 
inserted under the relevant item in the report. If nothing appears, it 
is usually because you changed the data block nameafter you inserted 
the VRF text, because the VRF header has to alsocontain the same name 
as the data block.  See my attached examples. L2201 is the data block 
header and the VRF also contains"L2201": _vrf_PLAT420_L2201
