Fprintf code errors

Holz

Hi,

I'm trying to expand the code in this thread, use SKILL script to save waveform and some global parameters in a file. In each file, after the waveform of signal is recorded, then record three global parameters, which are created in Monte Carlo simulation. The code is following:

(procedure (abDumpWaveform wave fileName rise_time fall_time plateau @optional (format "%g %g %f %f %f\n"))
(let (port (xVec (drGetWaveformXVec wave))
(yVec (drGetWaveformYVec wave))
(tr rise_time)
(tf fall_time)
(pl plateau)
)
(unless (setq port (outfile fileName))
(error "Could not write to file %s\n" fileName))
(for pos 0 (sub1 (drVectorLength xVec))
(fprintf port format
(drGetElem xVec pos)
(drGetElem yVec pos)

)
)
(fprintf (port "%f %f %f tr tf pl"))
(close port)
))


And the expression in ADE XL is:

(abDumpWaveform(VT("/net2") strcat(openResults() "/dump.txt") VAR("tr") VAR("tf") VAR("pw")) && 1)


However, I get errors :

ERROR (ADE-2708): Evaluation of output '(abDumpWaveform(VT("/net2") strcat(openResults() "/dump.txt") VAR("tr") VAR("tf") VAR("pw")) && 1)' failed for point:'1' test:'rvt_test:ptl_test:1'
\o Expression:'(abDumpWaveform(VT("/net2") strcat(openResults() "/dump.txt") VAR("tr") VAR("tf") VAR("pw")) && 1)'
\o because of the following error(s)
\o *Error* fprintf/sprintf: too many format specs..
\o Ensure that the definition of output is correct.

It seems like this piece of code : fprintf (port "%f %f %f tr tf pl")) is wrong, right? How can I correct it?

Thanks a lot for the help!

    Hi,

    The fprintf call is in fact messy. fprintf expects at least 2 arguments, an output port and a format string. Plus - for each placeholder in the format string an additional argument must be provided. I guess what this is to supposed to look like is this:

    (fprintf port "%f %f %f" tr tf pl)

    Another thing that doesn't look right is the fprintf statement a few lines further up:

    (fprintf port format
        (drGetElem xVec pos)
        (drGetElem yVec pos))

    The format string in this statement is in a variable named format that comes in as an optional parameter with the default value being "%g %g %f %f %f\n". There are 5 placeholders in this format string but the above fprintf statement defines just two expressions. So the default value for the format parameter should be (format "%g %g\n")
