How to export the plot of delay versus temperature to a ASCI

[Bob WU]

Dear All,

Now I want to simulate the time delay of an inverter under different
temperatures in Cadence, so I set the "tran" as the analyses type,
define a "delay" function as my outputs, then use the "parametric
analysis" to sweep the temperature to get the plot. Now I want to
export this obtained plot to a data file, so I can make a data
fitting. But how to export the plot to a file? Now the cadence doesn't
have WaveScan, so I think I need a ocnscript to make it. Any one can
throw some light on this and tell me how I can go about this.

Best regards,
Bob

You can use the "printvs" button in the calculator, and the "print" the
resulting window to a file.

Or you can use the ocnPrint() function to print the expression to a file, for
example:

openResults("/path/to/results/dir/psf")
selectResult('tran)
data=v("whatever")
ocnPrint(?output "ascii.out" data)
