Way to detect a edge in a intreval using H Spice

[Ravinder487]

Hi all,

Is there any way in H Spice to detect whether there is an edge in a given Interval i.e in a specified time range?
Thanks in advance.

Use the FIND & WHEN commands, s. here the appropriate pages from an HSPICE command reference: View attachment hspice_command_ref_p_2-104--2-106.pdf

Something like:
.MEAS TRAN is_edge FIND time AT=<interval_start> WHEN out_var CROSS=1

You'll probably have to try & error a little bit.

Thanks Erikl.... I use the same command to find edge after certain time(interval_start) but my Intention is to find edge after t1 and before t2(t2>t1)

Try something like:

.MEAS TRAN edge_found TRIG AT=<interval_start> TARG AT=<interval_end> <signal> CROSS=LAST

Try & err a bit ;-)
