Implement CSR accessors for all standard integer types and

Rename accessors to better reflect the size of the register
being accessed, and correspondingly update the generation
of "csr.h" in "export.py".
Additionally, provide read/write accessors that superimpose arrays
of standard unsigned C types over a CSR register (which may itself
be spread across multiple subregisters).

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.

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

The SPI mode is actually mode3, since the output value is updated on the

This also clarifies some of the documentation based on experience with
the core.

It was necessary to add drp_locked CSR for reading LOCK signal from
MMCM. Additionally, input signal RESET from MMCM was not driven by
any signal to do a proper reset of MMCM module thus it was impossible
to perform entirely correct dynamic clock reconfiguration.

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.

builder: use the SoC's existing shadow base with get_csr_header()
...
Both the SoC and get_csr_header() have independently set defaults
for the value of 'shadow_base'. If the SoC's value was modified,
ensure that get_csr_header() uses the modified value instead of
its own default.

trellis, versa_ecp5: optional '-nowidelut' flag for yosys synth_ecp5
...
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.

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.

software: use native toolchain for same host, target architectures
...
LiteX rightfully assumes that most often the target software must
be cross-compiled from an x86 host platform. However, LiteX can be
also built on a 'linux-riscv64' platform (e.g. Fedora's riscv64
port), where the software for riscv64 targets should be compiled
using the native toolchain.

soc/core: simplify/cleanup HyperRAM core
...
- rename core to hyperbus.
- change layout (cs_n with variable length instead of cs0_n, cs1_n).
- use DifferentialOutput when differential clock is used.
- add test (python3 -m unittest test.test_hyperbus).
Usage example:
from litex.soc.cores.hyperbus import HyperRAM
self.submodules.hyperram = HyperRAM(platform.request("hyperram"))
self.add_wb_slave(mem_decoder(self.mem_map["hyperram"]), self.hyperram.bus)

soc_core: optimize mem_decoder
...
Non-optimized version was tested on 7-series and was additional resource usage
was not noticeable. This does not seems to be the case on iCE40 (see #220 ), so
hand optimize it. On 256MB aligned addresses, it should be equivalent to the
old decoder used by previously in LiteX.
The only requirement is that to have address aligned on size, which was already
the case. An assertion will trigger it this condition is not respected.

tools/litex_sim: fix default endianness for mem_init
...
Initializing ROM and/or RAM content requires knowing the CPU
endianness before the SimSoC->SoCSDRAM->SoCCore constructor
sequence is invoked (before the SoC's self.cpu.endianness
could be accessed). Given that the majority of supported CPU
models use "little", set it as the new default, and override
only for the two models that use "big" endianness.

bios: Fix build when ethphy is present but ethmac is not.

While testing my Ethernet DMA, I renamed the `ethmac` module to `ethmac_dma` so that it wouldn't be used from the BIOS, but I got an undefined reference to `eth_init` because `bios.c` checks different CSR defines than the code that defines `eth_init`.

2019-04-26 18:57:49 -05:00
71a837315a
Work with no `cpu_variant` provided.
2019-04-26 17:44:36 -05:00
39c579baa2
Standardize the `cpu_variant` strings.
...
Current valid `cpu_variant` values;
* minimal (alias: min)
* lite (alias: light, zephyr, nuttx)
* standard (alias: std) - Default
* full (alias: everything)
* linux
Fully documented in the [docs/Soft-CPU.md](docs/Soft-CPU.md) file
mirrored from the
[LiteX-BuildEnv Wiki](https://github.com/timvideos/litex-buildenv/wiki ).
Also support "extensions" which are added to the `cpu_variant` with a
`+`. Currently only the `debug` extension is supported. In future hope
to add `mmu` and `hmul` extensions.

versa_ecp5: Remove negative diff IO pins
...
In Lattice FPGAs only the positive side of differential pairs should
be specified (unlike Xilinx)
These are a warning on Diamond (which trims unused IO) and an error
with Yosys/nextpnr (which doesn't so they conflict when the positive
pin is 'expanded').
Already this is the case for the clock input, this commit performs
the same change for the DDR3 pins.
