How to output time value at a specified voltage?

Carmichaeli
Hi, everyone
I have a question when I use Ocean.
I can output the voltage value of S<44> at the time of 19ns when I use the statement:
fprintf(cal "%f \n" value(v("/S<44>" ?result "tran-tran") 19n)).
But if I want to output the timing points in some specified voltage for a simulation, what should I do? I mean, for example, I want to know what time the voltage value of a waveform can reach 0.9V. Maybe there exists more than one value at which voltage is 0.9V throughout the waveform. It is OK when just one time value is acquired in a specified time range.
 
Thanks in advance!

    Wayne,

    The cross function is what you want.
