How to export assembler measurement waveform to csv/vcsv files?

I am usually plotting the waveform and then RMB on the plot and then Send To->Export

The problem is I have PVT sweep and want to group waveforms to files by one of the parameters and it takes a long time to do it manually

There is a SKILL function awvSaveToCSV() that will export a waveform or a list of waveforms in a comma-separated variable (CSV) formatted file. It is documented in the ViVA XL Skill Reference manual. From that manual, the syntax of the command is:

awvSaveToCSV(
l_waveforms
t_fileName
[ ?from x_from ]
[ ?to x_to ]
[ ?precision x_precision ]
[ ?step x_step ]
[ ?linLog t_linLog ]
[ ?exprList l_expressionList ]
[ ?mergeXAxis g_mergeXAxis ]
)
=> t / nil

Hence, you could either use it in a SKILL script to execute following the completion of your set of PVT simulations or, alternately, include an ocean script that contains this function as an output that will export the waveform(s) you want to a CSV file. You can add an ocean script measurement to your Assembler/Explorer test. You might want to refer to the link provided by Mr. Andrew Beckett regarding using an ocean script following an Assembler/Explorer run at URL:

@ShawnLogan thank you. But this function needs waveform to work. How can i pass a waveform of measurement from specific corner/sweep?

As I mentioned in my response, you may use the function in an ocean script and include the ocean script as an ADE output. There is some information about saving data in a text file using an ocean script in the Forum post at URL:

Dear alexstepanov75,

I happen to realize I may not understand your objective. I thought you wanted a means to send a waveform to a CSV file following the completion of a simulation in ADE Assembler. You were plotting the waveform you wanted to save to a ViVA window manually and then exporting that waveform to a CSV file.

If that is the case, you create an oceanXL script that runs after your simulation completes in ADE Assembler that uses the awvSaveToCsv() function with the name of the waveform you want to export to the file.

An alternative is to run an ocean script after your PVT simulations are complete. The ocean script will traverse all the simulations in the test and print the relevant waveforms to a file. I have posted an example ocean script that traverses an ADE Assembler database and will allow you do to use the awvSaveToCsv(0 function to export the relevant waveform. SInce it is an ocean script, you can include condiitonal expressions to, for example, only print the waveform if one or more conditions are met. There are links to the sample ocean script (with comments as to how to use it in your application/environment) in the post at URL:

Within that post,I refer to the post at URL:

https://community.cadence.com/cadence_technology_forums/f/custom-ic-design/43159/way-to-use-skill-script-to-save-waveform-into-a-file-in-ade-xl-run

which contains the script.

I hope this helps you!
