Export and import GDS using SKILL in batch mode

Sherl

Hi all,

I want to export the GDS file from the library and import the GDS file into another library. Does SKILL support importing and exporting GDS files in batch mode?

Best regards,

Huy Hoang

  • Hi Huy,

    You can use xstSetField to set the parameters, and then xstOutDoTranslate to do the export. Then xstInSetField and xstInDoTranslate to do the import.

    Note that going via stream (aka GDS) is a lossy operation (you lose connectivity and various other non-physical aspects, and pCells get converted to fixed cells), so if this is just a means of copying data from one library to another, you'd be better off using the ccp.* functions to copy instead.

    Regards,

    Andrew.

    Hello Andrew

    So far I have been using the "system(strmout ……... )" skill APIs to export the GDS files. These xst* APIs are new to me but seems like very useful for my next scripts.

    It would be very useful if you could provide us a sample scripts to do stream out/in using the xst* skill APIs. 

    Thanks and Regards

    Hi Saurabh,

    This is mostly pretty obvious from reading the documentation, but here's a simple example of doing a stream out (and suppressing the completion dialog box):

    xstSetField("library" "opamp090")
    xstSetField("topCell" "adc_sample_hold")
    xstSetField("strmFile" "adc_sample_hold.gds")
    xstSetField("showCompletionMsgBox" "false")
    xstOutDoTranslate()

    The documentation shows you how to find out the field names. The stream in would be similar (using xstInSetField instead and xstInDoTranslate).

    Andrew.
