But U15.18 has C156( 1 uF) so that encountered this asymmetry after added another two blocks of bypassing capacitors in rc2: C[240..245] and C[248..252]. as you suggested in #milkymist, we made mistakes without two rules i try to say they are 'rules'.: 1. to intensive components: bypassing capacitors editing, it would be important that given with the table that says what goes where, the layout will be properly defined, or 2. put respective pin numbering text beside those intensive components. added now this into http://en.qi-hardware.com/wiki/Rules_on_Editing_Schematics thanks for diggings. :) - adam
