Marcelina Kościelnicka 9a4f420b4b Replace opt_rmdff with opt_dff. 2020-08-07 13:21:03 +02:00
Marcelina Kościelnicka 6cd135a5eb opt_expr: Remove -clkinv option, make it the default. 
Adds -noclkinv option just in case the old behavior was actually useful
to someone.

Marcelina Kościelnicka cf60699884 synth_ice40: Use opt_dff. 
The main part is converting ice40_dsp to recognize the new FF types
created in opt_dff instead of trying to recognize the mux patterns on
its own.

The fsm call has been moved upwards because the passes cannot deal with
$dffe/$sdff*, and other optimizations don't help it much anyway.

Marcelina Kościelnicka 347dd01c2f xilinx: Fix srl regression. 
Of standard yosys cells, xilinx_srl only works on $_DFF_?_ and
$_DFFE_?P_, which get upgraded to $_SDFFE_?P?P_ by dfflegalize at the
point where xilinx_srl is called for non-abc9.  Fix this by running
ff_map.v first, resulting in FDRE cells, which are handled correctly.

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).

  * Synplify also supports `syn_rw_conflict_logic`, which is not

Limitations of the Yosys implementation:

    to case. There is currently no way to do this in Yosys (attrmap
    can only change case of attribute names).

Marcin Kościelnicki aff6ad1ce0 xilinx: Improve flip-flop handling. 
This adds support for infering more kinds of flip-flops:

- FFs with async set/reset and clock enable
- FFs with sync set/reset
- FFs with sync set/reset and clock enable

Some passes have been moved (and some added) in order for dff2dffs to
work correctly.

This gives us complete coverage of Virtex 6+ and Spartan 6 flip-flop
capabilities (though not latch capabilities).  Older FPGAs also support
having both a set and a reset input, which will be handled at a later
data.
