Why does Design Space Explorer II omit some clock domains in my design? - Why does Design Space Explorer II omit some clock domains in my design? Description Due to a problem in the Quartus® II software version 15.0 Update 1 and earlier, you may see clocks are missing from the list of clock domains in the Reports section in the Design Space Explorer II.
