Yes, the signal_rate option impacts the glitch analysis.
------- Probability Equation------
In ideal conditions, the toggle rate on an RTL node should meet this criterion:
If the given switching rate does not satisfy this equation, then it is treated as glitch data.
You can extract RTL toggle rate using the following:
For freq 100MHz
set_switching_activity -static_probability 0.7 -signal_rate 150 [get_ports d]
Given Toggle Rate = 150/100 = 1.5 = 150% - this given toggle Rate violates the above equation: 0.75 <= 0.7 <= 0.25
We need to extract the glitch component:
RTL Toggle Rate = 2*0.7(1-0.7) = 0.42 -> 42%
Therefore Glitch rate = 1.5 0.42 = 1.08
Once the glitch rate is identified, the glitch power analysis would be included in the general power analysis.
