Setting a manual delay on CLK/CMD vs DQ/DQS is required on some configuration to center the write leveling window:
Before (delay = 0 taps):
Write leveling:
m0: |11000000000000011111111111| delay: 15
m1: |00000000000000111111111111| delay: 14
m2: |11110000000000000111111111| delay: 17
m3: |11110000000000000011111111| delay: 18
m4: |11111111110000000000000111| delay: 00
m5: |11111111110000000000000111| delay: 00
m6: |11111111111000000000000001| delay: 00
m7: |11111111111000000000000011| delay: 00
After (delay = 12 taps):
Write leveling:
m0: |11111111111111000000000000| delay: 00
m1: |11111111111100000000000001| delay: 00
m2: |00011111111111110000000000| delay: 03

Add 'volatile' qualifier to new CSR accessors
...
Through their use of the MMPTR() macro, the "classic"
csr_[read|write]simple() accsessors identify the MMIO
subregister with the 'volatile' qualifier.
Adjust the new, csr_[rd|wr]_uint[8|16|32|64]() accessors
to also utilize the 'volatile' qualifier. Since accesses
are implicit (a[i], where a is an 'unsigned long *'),
change 'a' to be a 'volatile unsigned long *' instead.
No difference was noticed in opcodes generated using the
gcc9 risc-v cross-compiler on x86_64 with standard LiteX
cflags (vexriscv and rocket were tested), but since
reports exist that 'volatile' matters on some combinations
of compilers and targets, add the 'volatile' qualifier just
to be on the safe side.

doc: fix regression with new irq manager

Previously, we were accessing the `soc.soc_interrupt_map` property in
order to be able to enumerate the interrupts. This has been subsumed
into a more general `irq` object that manages the interrupts.
Use `soc.irq.locs` instead of `soc.soc_interrupt_map` as the authority
on interrupts for both doc and export.
This fixes #385 .

be used) or let the SoC builder automatically find and allocate a memory region.

cores/clock/xadc: ease DRP timings
...
Hard IP blocks are fixed in location, so long/deep combinational paths routing to multiple hard IP blocks can lead to timing closure problems.
XADC and MMCM DRPs currently have their DEN pins triggered by the ".re" output of a CSR. This is asynchronously derived from a fairly complicated set of logic that involves a logic path that goes all the way back through the cache and arbitration mechanisms of the wishbone bus. On more complex designs, this is leading to a failure of timing closure for these paths, because the hard IP blocks can be located in disparate portions of the chip which "pulls" the logic cluster in opposite directions in an attempt to absorb the routing delays to these IP blocks, leading to non-optimal placement for everything else and thus timing closure problems.
This pull request proposes that we add a pipeline delay on these critical paths. This delays the commit of the data to the DRP by one cycle, but greatly relieves timing because the pipeline register can be placed close to the cluster of logic that computes addresses, caching, and arbitration, allowing for the routing slack to the hard IP blocks to be absorbed by the path between the pipe register and the hard IP block.
In general, this shouldn't be a problem because the algorithm to program the DRP is to hit the write or read CSR, and then poll the drdy bit until it is asserted (so the process is already pretty slow). The MMCM in particular should have almost no impact, because MMCM updates are infrequent and the subsequent lock time of the MMCM is pretty long. The XADC is potentially more problematic because it can produce data at up to 1MSPS; but if sysclk is around 100MHz, adding 10ns to the read latency is relatively small compared to the theoretical maximum data rate of one every 1,000ns.
Note that the xadc patch requires introducing a bit of logic into the non-DRP path. This is because without explicitly putting an "if" statement around the logic, you fall back to the non-blocking semantics of the verilog operator, which ultimately leads to a pretty hefty combinational path. By having a default "if" that should get optimized out when DRP is not enabled, when the DRP path /is/ enabled the synthesizer knows it can safely push the async signal into a simple mux as opposed to worrying about enforcing the non-blocking operator semantics to get the desired result.

soc/cores/xadc: define analog_layout and simplify analog_pads connections
2020-01-06 16:28:48 +01:00

bring back analog_pads specifier, remove reset conditions on VP
...
For the "P" side of the analog channels, actually, connecting
a digital line to them has "no meaning". The docs say that
either you connect an analog pin to a pad, or vivado "ties it off
appropriately". I wish it were the case that tying a pin to 0 or 1
would actually connect it to a power or ground, because it means
that even in unipolar mode you have to burn two pins to break out
the signal of interest *and* the ground reference analog pad
(I thought I could just connect it to "0" and the pin would be
grounded, but that doesn't happen -- it's just ignored if it's
not wired to a pad).
For the pad specifier, is it OK to leave it with an optional
argument of analog_pads=None? I tried assigning to the
self.analog property after instantiation, but this doesn't
seem to work, the default values are preferred. It looks like
if you don't want to do the analog_pads= optional argument
the other way to do it would be to add code on the instiating
module that tampers with the properties of the instance directly,
but I think that's sort of ugly.
Also, I noticed you stripped out the layout specifier for
the analog_pads. I thought it would be nice to provide that
in the file, so the caller doesn't have to infer what the
pad layout is by reading the code...what's the motivation for
removing that?

add support for DRP on XADC
...
The design is backward-compatible in functionality for users
who don't want to use DRP. That is, on power on, the XADC will
scan the supply and temperature and store them in CSRs.
If drp_enable is set, the scanning stops, and the XADC is now
controlled by the DRP bus.
Wher drp_enable is reset, the XADC may return to an auto-sample
mode, but only if the internal registers are configured to do this.
If you return to drp_enable without, for example, turning on
the continuous sequence and setting which channels to check,
the results will be unpredictable (mostly either it'll scan just
once and stop, or it'll not scan all the channels, depending on
the register settings).
At this point, the backward compatibility was confirmed in testing,
the DRP API is still a work in progress as the application this
is being developed for needs to support fun stuff like real time
sampling of signals to a buffer.
Down the road, this block may have to be modified again to support an
output FIFO, so we're not railing the CPU trying to do real time
sampling of ADC data. This will probably be added as a True/False flag
of some sort in the parameter list, because the FIFO will be expensive
as far as BRAM goes to implement and applications that don't need the
FIFO buffer can probably use that BRAM for better things.

memory port and LiteDRAM can be accomplished without any additional

soc_core: csr_alignment assertions

Enforce the condition that csr_alignment be either 32 or 64 when
requested explicitly when initializing SoCCore().
Additionally, if a CPU is specified, enforce that csr_alignment be
equal to the native CPU word size (currently either 32 or 64), and
warn the caller if an alignment value *higher* than the CPU native
word size was explicitly requested.
In conclusion, if a CPU is specified, then csr_alignment should be
assumed to equal 8*sizeof(unsigned long).

soc/interconnect/packet: add > 8-bit support to Packetizer/Depacketizer
...
With high speed link (10gbps XGMII ethernet for example), stream data_width is generally
> 8-bit which make header/data un-aligned on bytes boundaries. The change allows the
Packetizer/Depacketizer to work on stream with a data_width > 8-bit.

cpu/rocket: parameterize axi interface data width
...
Rocket variants can be configured with axi port data widths that
are multiples of the native word size (64 bits in our case). In
the future, we will add variants with mem_axi data width > 64 bit,
to match the native data width of the LiteDRAM controller on
various development boards (e.g., 128 bits on the ecp5versa, and
256 bits on the trellisboard).

cpu/rocket, soc_sdram: Connect mem_axi to LiteDRAM, bypass WB bus
...
Connect Rocket's dedicated port for cached RAM accesses (mem_axi)
directly to the LiteDRAM data port, bypassing the shared LiteX
(Wishbone) bus.
When both Rocket's mem_axi and LiteDRAM's port have the same data
width, use a native point-to-point AXI connection.
Otherwise, convert both ends to Wishbone, and use the Wishbone
data width converter to bridge the gap.
FIXME: In the future, this part should be replaced with a native
AXI data width converter!

build/lattice/trellis: optionally allow failure if p&r timing not met
...
When timing requirements are strict, allow the build process to fail upon
failure to meet timing. This facilitates running the build process from a
loop, repeatedly, until a "lucky" p&r solution is found, e.g.:
while true; do
litex/boards/targets/versa_ecp5.py --gateware-toolchain trellis \
--sys-clk-freq=60e06 --cpu-type rocket --cpu-variant linux \
--with-ethernet --yosys-nowidelut \
--nextpnr-timingstrict
if [ "$?" == "0" ]; then
echo "Success" | mail -s "Build Succeeded" your@email.here
break
fi
done
This augments commit #683e0668, which unconditionally forced p&r to
succeed, regardless of whether timing was met, via '--timing-allow-fail'.

cpu/rocket: swap main_mem and io regions
...
The total size of RAM (main_mem) can be expected to vary significantly,
and often exceed the size needed for MMIO allocations by a large margin.
As such, place Rocket's MMIO (io regions) below 0x8000_0000, and start
the RAM (main_mem) at 0x8000_0000, with nothing above it to limit its
future growth.
Also, bump the pre-built Rocket verilog submodule to an updated version,
which also comes with matching changes to the way MMIO and RAM accesses
are mapped and routed to their respective AXI interfaces.

soc_core/cpu: add io_regions and deprecate shadow_base (with API retro-compat)
...
The shadow_base parameter has always been difficult to apprehend, replace it with
io_regions (uncached regions) defined user or the CPU.
The equivalent of a shadow_base parameter of 0x80000000 in the old API is:
io_regions = {0x80000000: 0x80000000} # origin, length
It's still possible to use shadow_base with retro-compat, but user is encouraged
to update and features will be removed in the future.

Passing '-nowidelut' to yosys' synth_ecp5 command improves area utilization
to the point where a (linux variant) rocket-chip based design will fit on a
versa_ecp5 board. Usually '-nowidelut' incurs a timing penalty, but that is
then mitigated by using DSP inference (enabled by default from yosys commit
8474c5b3).
Off by default, this flag can be enabled by adding '--yosys-nowidelut=True'
to the litex/boards/targets/versa_ecp5.py command line.

wishbone2csr: refactor using FSM, reduce latency (make it asynchronous) and set csr.adr only when access is done (allow use of CSR/CSRBase we signal)
...
Making it asynchronous does not seem to deteriorate timing or resource usage, if it's the case for some designs, we'll add a register parameter.

csr: add we signal to CSR, CSRStatus
...
Doing actions on register read is generally not a good design practice (it's
better to do separate register write to trigger actions) but in some very
specific cases being able to know that register has been read can solve cases
that are difficult to do with the recommended practives and that can justify
doing an exception.
This commit add a we signal to CSR, CSRStatus and this allow the logic to know
when the CSR, CSRStatus is read.

integration: add ModuleDoc and AutoDoc
...
It is important to be able to document modules other than CSRs.
This patch adds ModuleDoc and AutoDoc, both of which can be used
together to document modules.
ModuleDoc can be used to transform the __doc__ string of a class into a
reference-manual section. Alternately, it can be used to add additional
sections to a module.
AutoDoc is used to gather all submodule ModuleDoc objects in order to
traverse the tree of documentation.

csr_eventmanager: add `name` and `description` args

Add `name` and `description` as optional arguments to the various
EventSource types. These default to `None`, so this should be a
backwards-compatible change.
Use the same trick as CSRs, where we default the `name` to be the
instantiated object name as read from the Migen `get_obj_var_name()`
call.
