The CALICE collaboration is developing highly granular electromagnetic
and hadronic calorimeters for a future high energy electron positron
linear collider. We present a conceptual design for a scintillator
tile HCAL with SiPM readout. As a first step, a cubic-meter sized
physics prototype has been constructed and operated successfully in
the CERN SPS test beam; results have been submitted to this
conference. In contrast to the test beam HCAL, a realistic calorimeter
has to be compact and must have minimal dead zones. The design presented
is based on highly integrated, ultra-low power read-out ASICs
embedded in the active detector layers with minimized thickness. A
scheme for integrating an optical calibration system without light
transmission fibers is also proposed. Mechanical, thermal, electronics
and DAQ solutions are discussed, and results for component tests are
