Title: how to record the zero-crossing timing points
Post by jfyan on May 29^th, 2005, 6:55am

hi all:

how can i record the zero-crossing timing points in spectre to a voltage wave?
i mean, i want to put down the wave's every zero-crossing times in transient analysis.

thanks in advance.

In OCEAN, you can do:

selectResult('tran)
crosses=cross(v("/out") 0.0 0 'either)

The 0.0 is the threshold level, 0 tells it to output all crossings,
and 'either specifies both rising and falling.

The result will be a list.

See the OCEAN documentation for more details on what to do with the result!

Regards,

Andrew.
