 +We made initial schematic in kicad.
 +
 +Next define electric bla bla in pcm3168A component. Make sure that every pins are connected to something (mark unused as unused). Continue until electrical rule check is passed.
 +
 +When this is done figure out how to make PCB.
 +
 +=====2018-02-27=====
 +We (re)started working with kicad to define the PCM and FPGA chips.
 +
 +Information about the component library file format:
 +http://kicad-pcb.org/help/file-formats/
 +
 +We are considering using the iCE40 Ultra (iCE5LP4K) instead of the iCE40HX8K.
