  • Hi there,

     

    I wish to write a simple ulp that generates a script.

     

    I know what I want the script to say (a simple series of name commands), generated using a couple of inputs (a starting index and the desired naming prefix).

     

    I need to run similar scripts for different starting inputs over 70 times to cover all the replicated blocks on my board, so I want to write a ulp to generate the script for me.  I know this should be straightforward, but I'm quite unfamiliar with the syntax etc.

     

    I have the user language manual, which is helpful but a little overwhelming when first starting!  I'm just hoping someone could point me to a simple ulp that takes a couple of inputs and generates a script that I can look at as an example.  I'm getting hopelessly lost looking at some of the bigger ulps which are doing all sorts of fancy things I don't need at this point...

     

    Any assistance appreciated - feel free to point me to previous discussion on this point if there is one that I've failed to find.

     

    Many thanks,

    Anna

     

    EDIT: I have spent the day playing and have finally managed to write a ulp that successfully generates the required scripts. So, no need to respond to this query.

    Thanks for this helpful thread though!  I would like to suggest that a tutorial on ulp-writing would be a helpful addition to the available documentation in future.

    Regards,

    Anna

    Hi Anna,

     

    there a ULPs that generate a script file that will be executed automatically. Look into my posting some messages above repying to KSz. There is you can see some lines of change-via-by-stack.ulp that might help. By the way: The User Lanugae is completely documented in the EAGLE help. You can also download this part of the help as PDF from http://www.cadsoft.de/downloads/documentation/

    There an ulp5110-en.pdf available.

     

    Hope this helps.

    Regards,

    Richard
