2013.3 Vivado Power - How much hierarchy does the 'read_saif' remove when matching the SAIF to the design?

Description

How much hierarchy does the 'read_saif' remove when matching the SAIF to the design?

Solution

The 'read_saif' command reads the SAIF file, and strips off the first two levels of hierarchy in the SAIF and tries to match the design nets. Once the nets are matched, then the activity rates are applied to that node.

If your SAIF file has more than two levels of hierarchy before the top of the design is determined, then you must use the -strip_path option.

Three levels of hierarchy in the SAIF example: read_saif -strip_path /br_test_top/br_dut_wrapper/br_top -out_file saif_output_file.rpt my_simulation.saif.
