Icenowy Zheng c9513c695a Anlogic: let LUT5/6 have more cost than LUT4- 
According to the datasheet of Anlogic Eagle FPGAs, The LUTs natively
in an Anlogic FPGA is LUT4 (in MSLICEs) and "Enhanced LUT5" (in
LSLICEs). An "Enhanced LUT5" can be divided into two LUT4s.

So a LUT5 will cost around 2x resource of a LUT4, and a LUT6 will cost
2x resource of a LUT5.

Change the -lut parameter passed to the abc command to pass this cost
info to the ABC process.

Icenowy Zheng 634d7d1c14 Revert "Leave only real black box cells" 
This reverts commit 43030db5ff.

For a synthesis tool, generating EG_LOGIC cells are a good choice, as
they can be furtherly optimized when PnR, although sometimes EG_LOGIC is
not as blackbox as EG_PHY cells (because the latter is more close to the
hardware implementation).

whitequark 7ff5a9db2d equiv_opt: pass -D EQUIV when techmapping.

 2018-12-07 17:20:34 +00:00
Olof Kindgren 889297c62a Only use non-blocking assignments of SB_RAM40_4K for yosys 
In an initial statement, blocking assignments are normally used
and e.g. verilator throws a warning if non-blocking ones are used.

Yosys cannot however properly resolve the interdependencies if
blocking assignments are used in the initialization of SB_RAM_40_4K
and thus this has been used.

This patch will change to use non-blocking assignments only for yosys

whitequark 1719aa88ac Extract ice40_unlut pass from ice40_opt. 
Currently, `ice40_opt -unlut` would map SB_LUT4 to $lut and convert
them back to logic immediately. This is not desirable if the goal
is to operate on $lut cells. If this is desirable, the same result
as `ice40_opt -unlut` can be achieved by running simplemap and opt
after ice40_unlut.

Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)

Olof Kindgren faac2c5595 Avoid mixing module port declaration styles in ice40 cells_sim.v 
The current code requires workarounds for several simulators
For modelsim, the file must be compiled with -mixedansiports and
xsim needs --relax.

Tim 'mithro' Ansell d6bdefd2e9 Improving vpr output support. 
* Support output BLIF for Xilinx architectures.
 * Support using .names in BLIF for Xilinx architectures.
 * Use the same `NO_LUT` define in both `synth_ice40` and
  `synth_xilinx`.

Robert Ou 14e49fb057 coolrunner2: Add an ANDTERM/XOR between chained FFs 
In some cases (e.g. the low bits of counters) the design might end up
with a flip-flop whose input is directly driven by another flip-flop.
This isn't possible in the Coolrunner-II architecture, so add a single
AND term and XOR in this case.
