hi,i have a question about calculator function.Q1: i used to use in hspice the .measure statement offind v(a) when v(b)=v(c)but i don't know what function could acheive the same function in the ADE calculator. Q2: i am also trying to find the delay from whenv(b) crosses v(c) to when v(a)=0.9v (for example)how can i do this in the calculator? I appreicate any help. thanks.Frank
Something like this:
A1. value(VT("/a") cross(VT("/b")-VT("/c") 0.0 1 "either"))
A2. cross(VT("/a") 0.9 1 "either")-cross(VT("/b")-VT("/c") 0.0 1 "either")
In reply to Andrew Beckett:
thanks Andrew, i will give it a try now.
is there a way to tell the calculator to wait T seconds, before doing the evaluation?
In reply to potsticker:
Why would you want to do that? Sounds a bit odd to me... (there is a way, but I doubt very much that this is really what you want to do). Perhaps you can explain exactly what you're trying to do?
it is because it takes 10us for the transient waveform to stabilize to generate proper waveform.
i was able to later use the delay function which allowed me to specify the start time for the measurement. thanks.
Ah, I thought you were talking about a real time delay rather than simulation time...
You can also use functions such as clip to extract just a portion of the waveform.
