Florent Kermarrec 3d3bf623aa frontend/fifo: Simplify, fix corner cases. 2021-09-23 23:22:51 +02:00
Florent Kermarrec dd24073633 test/test_fifo: Use 4 x DRAM data-width in Bypass mode to use Pre/Post-Converter. 2021-09-23 18:57:00 +02:00
Florent Kermarrec 2d4a47f260 frontend/fifo: Add initial optional/automatic Bypass implementation to LiteDRAMFIFO.
Bypass will provide lower latency and configurable data-width.

Florent Kermarrec a3aa4907f1 phy/lpddr4/simsoc: Change cpu_variant to lite and revert commented test_lpddr4_sim_x2rate_no_cache.
(see #255).

Jędrzej Boczar fcda73a175 test/phy_common: simplify calls to run_simulation 2021-06-22 11:41:44 +02:00
Jędrzej Boczar da769094fd phy/lpddr4: fix edge case error with CommandsPipeline ignoring a command
Command was being ignored when it occurred on the last phase and
the next command would invalidate the first phase. Now it is fixed
and a regression test is included. A fix in ConstBitSlip has been added
due to wrong Verilog being generated with cycles=1, register=False.
2021-06-22 11:40:51 +02:00
Jędrzej Boczar baf9c07858 phy/utils: improve ConstBitSlip:
* optional register=False to decrease latency by 1 cycle
* require explicit `cycles` as it influences latency (min_cycles
  still can be used)
* add unit tests

Jędrzej Boczar ee9c2b4cf7 lpddr4: implement ZQC through MPC and include it in init sequence
We do not yet support ZQC during operation (after init sequence)
as LPDDR4 requires 2-stage ZQC (start+latch) and 1us in between,
which requires modifying Refresher (ZQCExecutor) in LiteDRAM.
