##      files in their own right for the purpose of testing the UART capability

##      of your board.  Should you wish to test these as toplevel files, you

##      will need to remove the i_setup from the input, and set it to something

##      like:

##              wire    [29:0]  i_setup;

##

##              // If we have a 100MHz clock, then we can set up for a 115,200

##              // baud clock by setting i_setup to (100MHz / 115200) ~= 868.

##              // The upper bits of this number also set the protocol to

##              // one stop bit, no parity, and 8 data  bits.

##              assign  i_setup = 30'd868;      // 115,200 Baud 8N1

##

##      Using this purpose, the UART ports of a new piece of hardware may be

##      proven.  To do this,

##              1. get BLINKY working first--to prove that the clock works like

##                      you think it does.  Then, once BLINKY is running,

##              2. get helloworld working.  This requires only the clock and

##                      the output UART pin to work.

##              (Aside) 3. Once helloworld works, you should be able to get

##                      speechfifo to work with no further hassles.

##              4. After helloworld works, switch to getting linetest running on

##                      your hardware.  This will prove that you have not only

##                      the clock and output UART pin working, but that you also

##                      have the input UART pin working as well.

##

## Targets:     The default target of this makefile, all, builds the target

##              test, which includes the linetest Verilator library, the

##      helloworld Verilator library, and the speechfifo Verilator library--all

##      necessary for bench testing using the C++ files in bench/cpp.
