Synthesis hierarchical report

[ndy2]

I want to get a synthesis report based on submodules.
For example in module NV_NVDLA_partition_c,
there are many submodules :

NV_NVDLA_reset
NV_NVDLA_sync3d
NV_NVDLA_sync3d
NV_NVDLA_sync3d_s
NV_NVDLA_sync3d_s
NV_NVDLA_cdma
NV_NVDLA_cbuf
NV_NVDLA_csc
NV_NVDLA_RT_csb2cmac
NV_NVDLA_RT_csb2cacc
NV_NVDLA_RT_cacc2glb
But when I add report_area -hierarchy to the dc_run.tcl file and run synthesis.
It gives a report with only one hierarchy: NV_NVDLA_partition_c

I try to resolve this on my own refer to
leo47007's TPU-Tensor-Processing-Unit : https://github.com/leo47007/TPU-Tensor-Processing-Unit/tree/master/8x8_ctime_3.01/syn/report

But I failed. :(
Help me please.
