 +
 +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.
 +=====2018-01-23=====
 +Somewthing about blocking and non-blocking assignment in verilog:
 +
 +  * https://class.ee.washington.edu/371/peckol/doc/Always@.pdf
 +
 +Today we decided that Verilog sucks and added vhd2vl to toolchain.
 +
 +Next time we will implement shiftregister in vhdl.
 +=====2018-01-16=====
 +Today we got two FPGAs working together as a serial coupled shift register. (The working code has been committed to git.)
 +
 +Next time we will double the clock rate output from the first to the second.

 Today we got it working. Now we have a working shiftregister. Today we got it working. Now we have a working shiftregister.
