Florent Kermarrec de2f1c31d5 sdram: create module.py to define SDRAM modules and use it on de0nano/ppro targets 2015-03-21 16:56:53 +01:00
Florent Kermarrec 6e4b7c6cfd sdram: split sdram_timing in sdram_timing_settings/sdram_controller_settings
req_queue_size, read_time, write_time settings are not sdram_timing settings but sdram controller settings

Florent Kermarrec b2f32ad124 targets/simple: manual instantiation of CRG (automatic insertion works for BaseSoC but not for MiniSoC since this one define clock_domains) 2015-03-17 01:07:44 +01:00
Florent Kermarrec 28d04ec300 soc: rename with_sdram option to with_main_ram (with_sdram was confusing) 2015-03-14 00:49:19 +01:00

Florent Kermarrec 2b9397ff5b targets: do not implement sdram if already provided by SoC (allow use of -Ot with_sdram = True) 2015-03-06 07:56:45 +01:00

Florent Kermarrec de698c51e4 sdram: rename self.phy_settings to self.settings (using phy.settings instead of phy.phy_settings seems cleaner) 2015-03-02 11:29:43 +01:00

Florent Kermarrec 1366ff5e26 move mxcrg to others (we should integrate it in mlabs_video.py and remove the verilog file in the future) 2015-02-28 11:51:51 +01:00
Florent Kermarrec 69e869893d remane GenSoC to SoC (more coherent and we will add support for multiple SoCs with their own Wisbbone/CSR buses in the future) 2015-02-28 11:36:15 +01:00
Florent Kermarrec 2c51adcd68 misoclib: better organization (create cores categories: cpu, mem, com, ...) 2015-02-28 09:40:44 +01:00
Florent Kermarrec 074f576340 targets: add de0nano (100MHz, integrated bios and SDRAM) 2015-02-27 19:47:32 +01:00
Florent Kermarrec 5e2e9338d2 bios: we can now use -Ot with_rom True on targets to force bios implementation in integrated rom (can speed up debug we don't want to reflash SPI or NOR flash) 2015-02-27 17:22:44 +01:00

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.
