Martin Povišer d6566eb344 booth: Redo baseline architecture summation 
Redo the summation logic: strive for some degree of balance on the
generated Wallace tree, emit an `$add` cell for the final summation.

Martin Povišer 48b73be8c6 booth: Replace the default signed architecture 
Generalize what was formerly the unsigned-only architecture to support
both signed and unsigned multiplication, use that as default, and set
aside the special low-power architecture that was formerly used for
signed multipliers.

Martin Povišer 579f6bdc17 booth: Do not special-case bottom rows 
Later on all the rows are cropped to the target size anyway, so there's
no harm in transitionally including extra top bits.

Martin Povišer fed2720999 synth_lattice: Optimize flip-flop memories better 
After `memory_map` maps memories to flip-flops we need to let `opt`
remove undef muxes, otherwise we block enable/reset signal inference by
`opt_dff` which is in detriment to QoR.
 2023-11-07 16:29:56 +01:00
Martin Povišer ee3a4ce14d synth_lattice: Merge NOT gates on DFF control signals 
`dfflegalize` will emit NOT gates to drive control signals on flip-flops
when mapping to supported flip-flop polarities. Typically in a design
this will produce a number of NOT gates driven by the same signal. For
one reason or another ABC doesn't fully cancel this redundancy during
LUT mapping. Insert an explicit `opt_merge` pass to improve synthesis
QoR.

Jannis Harder d415b4d98a cli: Cleanups for tcl argument handling 
* Keep the previous behavior when no tcl script is used
* Do not treat "-" as a flag but as a positional argument
* Keep including <unistd.h> as it's also used for other functions (at
  least for the emscripten build)
* Move the custom getopt implementation into the Yosys namespace to
  avoid potential collisions
