How to capture minimum spacing?

dgstan
dgstan over 13 years ago

I need to find the absolute minimum spacing defined in the Constraint Manager. This includes the CSets and any number manually entered in the CM, Region rules, Class/Class, etc. 

I see the function axlCNSGetSpacing will retrieve the values of your various CSets, but smaller numbers can be manually entered (i.e. not defined by a CSet) or set manually under region or class/class rules. Is there a way to derive this rock-bottom spacing value?

I tried to get that info via axlCnsTableSeek, but it doesn't seem to work period. 

 

Thanks in advance,

Douglas Stanley

    Hi Douglas,

    I achieve this by exporting a tech file,  parsing each section (using share\pcb\xml-formats\techfile.dtd) and analysing the results to find the minimum values. I would be interested if you find a more efficient method.

    Contact me off line if you want to share code.

    Cheers, Dave
