* | manual: fix typo. | whitequark | 2020-08-27 | 1 | -1/+1 |

* | Replace "ILANG" with "RTLIL" everywhere. | whitequark | 2020-08-26 | 3 | -16/+14 |
| | | | | | | | | | | The only difference between "RTLIL" and "ILANG" is that the latter is the text representation of the former, as opposed to the in-memory graph representation. This distinction serves no purpose but confuses people: it is not obvious that the ILANG backend writes RTLIL graphs. Passes `write_ilang` and `read_ilang` are provided as aliases to `write_rtlil` and `read_rtlil` for compatibility. | ||||

* | Add new builtin FF types | Marcelina Kościelnicka | 2020-06-23 | 1 | -28/+178 |
| | | | | | | | | | | | | | | The new types include: - FFs with async reset and enable (`$adffe`, `$_DFFE_[NP][NP][01][NP]_`) - FFs with sync reset (`$sdff`, `$_SDFF_[NP][NP][01]_`) - FFs with sync reset and enable, reset priority (`$sdffs`, `$_SDFFE_[NP][NP][01][NP]_`) - FFs with sync reset and enable, enable priority (`$sdffce`, `$_SDFFCE_[NP][NP][01][NP]_`) - FFs with async reset, set, and enable (`$dffsre`, `$_DFFSRE_[NP][NP][NP][NP]_`) - latches with reset or set (`$adlatch`, `$_DLATCH_[NP][NP][01]_`) The new FF types are not actually used anywhere yet (this is left for future commits). | ||||

* | Use in-tree include directory in manual build | Xiretza | 2020-05-30 | 1 | -1/+4 |
| | | | | | | | | This is basically the same issue as in tests/various/plugin.sh, which uses yosys-config to compile a plugin. `yosys-config --cxxflags` points to `$PREFIX/share/` (/usr/local/share by default), which might not exist yet or might be out of date. Building directly from the headers in ./share/ avoids this. | ||||

| * | Add flooring division operator | Xiretza | 2020-05-28 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | The $div and $mod cells use truncating division semantics (rounding towards 0), as defined by e.g. Verilog. Another rounding mode, flooring (rounding towards negative infinity), can be used in e.g. VHDL. The new $divfloor cell provides this flooring division. This commit also fixes the handling of $div in opt_expr, which was previously optimized as if it was $divfloor. | ||||
| * | Add flooring modulo operator | Xiretza | 2020-05-28 | 1 | -1/+1 |

Another rounding mode, flooring (rounding towards negative infinity), can be used in e.g. VHDL.

* | | Restrict RTLIL::IdString to not contain whitespace or control chars. | whitequark | 2020-05-29 | 1 | -3/+6 |
|/ | | | | | This is an existing invariant (most backends can't cope with these) but one that was not checked or documented. | ||||

* | Get rid of dffsr2dff. | Marcelina Kościelnicka | 2020-04-15 | 1 | -198/+2300 |
| | | | | | | This pass is a proper subset of opt_rmdff, which is called by opt, which is called by every synth flow in the coarse part. Thus, it never actually does anything and can be safely removed. | ||||

* | Consistent use of 'override' for virtual methods in derived classes. | Henner Zeller | 2018-07-20 | 2 | -4/+4 |
| | | | | | | | | | 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) | ||||
