Sebastien Bourdeauducq e53fb88b85 uart: minor cleanup and fix 2014-10-10 15:33:27 +08:00
Florent Kermarrec 5e5f436aa6 uart: split it and use dataflow
This make the code easier to understand and allow the reuse of UARTRX & UARTTX
on designs without CPU (e.g miscope).

Florent Kermarrec ba30a01830 mila: fixes when used without RLE 2014-10-06 12:30:06 +02:00
Florent Kermarrec f72f11f7b4 mila: add clk_domain support
an AsyncFIFO is inserted when clk_domain is not "sys" to enable capture from another clock domain.
sys_clk frequency need to be greater than clk_domain clock.

future possible improvement: automatic insertion of a converter when clk_domain frequency is
greater than sys_clk.

Florent Kermarrec c27f24c4c0 reorganize code
- use sys_clk of 166.66MHz and using it instead of sata clk.
- rename clocking to CRG since it also handles resets.
- create datapath and move code from gtx.

Florent Kermarrec 387cf90cf8 host and device communicate with OOB, now need to fix ctrl 2014-09-26 23:30:30 +02:00
Florent Kermarrec 01da43ecb2 reset and lock of PLL OK. We see OOB signals on the link but they are not decoded by the device. 2014-09-26 22:31:32 +02:00
Florent Kermarrec dfbec91a62 add modelsim simulation and start fixing init 2014-09-26 17:05:05 +02:00
Florent Kermarrec e03091e7e2 add generic CRCEngine, CRC32, CRCInserter and CRCChecker
CRCEngine implements a generic and optimized CRC LFSR. It will enable generation of CRC generators and checkers.
CRC32 is an implementation of IEEE 802.3 CRC using the CRCEngine.
CRC32Inserter and CRC32Checker have been tested on an ethernet MAC.

Florent Kermarrec c1fc0b9c97 update README with new Kintex-7 support 2014-09-26 10:36:29 +08:00
Florent Kermarrec 13fb9282db targets: add simple design (vendor agnostic and usable on all platforms with UART pins).
Designing a SoC with Migen is easy, but we have to provide a very simple design that can
be used on all boards with only 1 clock and 2 UARTs pins defined. This will encourage the
newcomer to invest time in Migen/MiSoC and see its real potential.
