PT中toggle rate的设定顺序

我在PT里report_power的时候发现设register和clock gating cell的toggle rate顺序调换一下report就会有很大差别。
那么实际上PT设toggle rate的顺序应该是什么呢?
set_switching_activity -toggle_rate 0.05 -clock_domains [all_clocks] -type registers -hierarchy -static_probability 0.5
set_switching_activity -clock_derate 1.0 -clock_domains [all_clocks] -type clock_gating_cells
