Sometimes it is necessary/recommended to partition (separate) power or ground planes, i.e. for ADC or DC/DC-Converters, see page 16 and 17 in
http://focus.ti.com/lit/ug/slwu028c/slwu028c.pdf We can do this in pcb program with (adjoining) polygons. Disadvantage is, that if we change the size of one of the polygons we have to manually adjust the other sizes. A other method may be so divide a large polygon by copper clearing traces (with trace width zero). This is related to my question from http://archives.seul.org/geda/user/Sep-2008/msg00387.html but not identical. What is the best way to handle this?
