whitequark 2b92f12016 examples: add concise UART example. 
This example uses shift registers and counters instead of an explicit
FSM, which makes it very compact in terms of generated logic, and
more concise too.

whitequark 1b54eb80da vendor.board: split off into nmigen-boards package. 
The iCE40 programmers are also moved, since they're board-specific.
(It looks like iceprog isn't, but it only works with Lattice
evaluation kits.)

Fixes #80.

whitequark f417725b10 build.res: if not specified, request resource #0. 
This markedly differs from oMigen system, which would request
consecutive resources. The difference is deliberate; most resources
are singular, so it does not matter for them, and for resources where
it does matter, which pins are requested should not depend on order
of execution of `platform.request`.

whitequark ba0fcddb2c vendor.ice40_hx1k_blink_evn: implement. 2019-06-01 16:48:07 +00:00
whitequark aed2062101 Remove examples/tbuf.py. 
This example predates the plans for nmigen.build, and indeed
get_tristate and TSTriple no longer exist.

whitequark 44711b7d08 hdl.ir: detect elaboratables that are created but not used. 
Requres every elaboratable to inherit from Elaboratable, but still
accepts ones that do not, with a warning.

Fixes #3.
