Patrick Urban 76bf96d310 synth_gatemate: Fix fsm test 2021-11-13 21:53:25 +01:00
Patrick Urban acb993b27b Allow initial blocks to be disabled during tests 
Wrap initial blocks with a NO_INIT so that tests for archs without register initialization feature don't fail.

Marcelina Kościelnicka 15b0d717ed iopadmap: Add native support for negative-polarity output enable. 2021-11-09 15:40:16 +01:00
Marcelina Kościelnicka 4e70c30775 FfData: some refactoring. 
- FfData now keeps track of the module and underlying cell, if any (so
  calling emit on FfData created from a cell will replace the existing cell)
- FfData implementation is split off to its own .cc file for faster
  compilation
- the "flip FF data sense by inserting inverters in front and after"
  functionality that zinit uses is moved onto FfData class and beefed up
  to have dffsr support, to support more use cases

Marcelina Kościelnicka b98376884e test/arch/{ecp5,ice40}/memories.ys: Use read_verilog -defer. 
These parts keep rereading a Verilog module, then using chparam
to test it with various parameter combinations.  Since the default
parameters are on the large side, this spends a lot of time
needlessly elaborating the default parametrization that will then
be discarded.  Fix it with -deref and manual hierarchy call.

Shaves 30s off the test time on my machine.

Marcelina Kościelnicka 8740fdf1d7 ast: Use better parameter serialization for paramod names. 
Calling log_signal is problematic for several reasons:

- with recent changes, empty string is serialized as { }, which violates
  the "no spaces in IdString" rule
- the type (plain / real / signed / string) is dropped, wrongly conflating
  functionally different values and potentially introducing a subtle
  elaboration bug

Instead, use a custom simple serialization scheme.

Marcelina Kościelnicka d3b6b7fe98 xilinx: Fix attributes_test.ys 
This test pretty much passes by accident — the `prep` command runs
memory_collect without memory_dff first, which prevents merging read
register into the memory, and thus blocks block RAM inference for a
reason completely unrelated to the attribute.

The attribute setting didn't actually work because it was set on the
containing module instead of the actual memory.

Marcelina Kościelnicka eb76d35e80 memory_dff: Fix needlessly duplicating enable bits. 
When the register being merged into the EN signal happens to be a $sdff,
the current code creates a new $mux for every bit, even if they happen
to be identical (as is usually the case), preventing proper grouping
further down the flow.  Fix this by adding a simple cache.

Fixes #2409.

Marcelina Kościelnicka 50d532f01c techmap/shift_shiftx: Remove the "shiftx2mux" special path. 
Our techmap rules for $shift and $shiftx cells contained a special path
that aimed to decompose the shift LSB-first instead of MSB-first in
select cases that come up in pmux lowering.  This path was needlessly
overcomplicated and contained bugs.

Instead of doing that, just switch over the main path to iterate
LSB-first (except for the specially-handled MSB for signed shifts
and overflow handling).  This also makes the code consistent with
shl/shr/sshl/sshr cells, which are already decomposed LSB-first.

Fixes #2346.

Dan Ravensloft 5b779f7f4e intel_alm: direct LUTRAM cell instantiation 
By instantiating the LUTRAM cell directly, we avoid a trip through
altsyncram, which speeds up Quartus synthesis time. This also gives
a little more flexibility, as Yosys can build RAMs out of individual
32x1 LUTRAM cells.

While working on this, I discovered that the mem_init0 parameter of
<family>_mlab_cell gets ignored by Quartus.

Dan Ravensloft 2e37e62e6b synth_intel_alm: alternative synthesis for Intel FPGAs 
By operating at a layer of abstraction over the rather clumsy Intel primitives,
we can avoid special hacks like `dffinit -highlow` in favour of simple techmapping.

This also makes the primitives much easier to manipulate, and more descriptive
(no more cyclonev_lcell_comb to mean anything from a LUT2 to a LUT6).

whitequark 081d9318bc ecp5: add support for both 1364.1 and LSE RAM/ROM attributes. 
This commit tries to carefully follow the documented behavior of LSE
and Synplify. It will use `syn_ramstyle` attribute if there are any
write ports, and `syn_romstyle` attribute otherwise.
  * LSE supports both `syn_ramstyle` and `syn_romstyle`.
  * Synplify only supports `syn_ramstyle`, with same values as LSE.
  * Synplify also supports `syn_rw_conflict_logic`, which is not
    documented as supported for LSE.

Limitations of the Yosys implementation:
  * LSE/Synplify support `syn_ramstyle="block_ram,no_rw_check"`
    syntax to turn off insertion of transparency logic. There is
    currently no way to support multiple valued attributes in
    memory_bram. It is also not clear if that is a good idea, since
    it can cause sim/synth mismatches.
  * LSE/Synplify/1364.1 support block ROM inference from full case
    statements. Yosys does not currently perform this transformation.
  * LSE/Synplify propagate `syn_ramstyle`/`syn_romstyle` attributes
    from the module to the inner memories. There is currently no way
    to do this in Yosys (attrmvcp only works on cells and wires).

whitequark 3f4460a186 ice40: match memory inference attribute values case insensitive. 
LSE/Synplify use case insensitive matching.

whitequark fc28bf55aa ice40: add support for both 1364.1 and LSE RAM/ROM attributes. 
This commit tries to carefully follow the documented behavior of LSE
and Synplify. It will use `syn_ramstyle` attribute if there are any
write ports, and `syn_romstyle` attribute otherwise.
  * LSE supports both `syn_ramstyle` and `syn_romstyle`.
  * Synplify only supports `syn_ramstyle`, with same values as LSE.
  * Synplify also supports `syn_rw_conflict_logic`, which is not
    documented as supported for LSE.

Limitations of the Yosys implementation:
  * LSE/Synplify appear to interpret attribute values insensitive
    to case. There is currently no way to do this in Yosys (attrmap
    can only change case of attribute names).
  * LSE/Synplify support `syn_ramstyle="block_ram,no_rw_check"`
    syntax to turn off insertion of transparency logic. There is
    currently no way to support multiple valued attributes in
    memory_bram. It is also not clear if that is a good idea, since
    it can cause sim/synth mismatches.
  * LSE/Synplify/1364.1 support block ROM inference from full case
    statements. Yosys does not currently perform this transformation.
  * LSE/Synplify propagate `syn_ramstyle`/`syn_romstyle` attributes
    from the module to the inner memories. There is currently no way
    to do this in Yosys (attrmvcp only works on cells and wires).

whitequark 29d130dee9 ice40: remove impossible test. 
iCE40 does not have LUTRAM. This was erroneously added in commit
caab66111e, and tested for BRAM,
essentially a duplicate of the "dpram.ys" test.
