| |
| * glift: Replace `YS_OVERRIDE` with `override`.Alberto Gonzalez2020-07-011-2/+2
| |
| * glift: Add `-simple-cost-model` optionAlberto Gonzalez2020-07-011-20/+45
| | | | | | | | | | | | | | | | Rather than assigning specific weights to specific versions of taint tracking logic and summing the weights of all GLIFT cells, sum the following values for each GLIFT cell: - 0 if the associated hole/$anyconst cell value is non-zero, i.e. reduced-precision taint tracking logic is chosen at this cell - 1 if the associated hole/$anyconst cell value is zero, i.e. the full-precision taint tracking logic is chosen at this cell This simplified cost modeling reduces the potential for the QBF-SAT solver to minimize taint tracking logic area but significantly simplifies the QBF-SAT problem.
| * glift: Add `-instrument-more` option to add 4 more versions of taint ↵Alberto Gonzalez2020-07-011-44/+124

| * glift: Change command names to better represent their functions.Alberto Gonzalez2020-07-011-22/+22
| |
| * glift: Add `-create-imprecise` command, rename other commands, and re-work ↵Alberto Gonzalez2020-07-011-28/+54
| | | | | | | | the help text.
| * glift: Add replacement scoring and area minimization option.Alberto Gonzalez2020-07-011-3/+56

| |
* | bugpoint: avoid infinite loop between -connections and -wires.Catherine2021-12-151-1/+1
| | | | | | | | Fixes #3113.
* | Add clean_zerowidth pass, use it for Verilog output.Marcelina Kościelnicka2021-12-122-1/+212
| | | | | | | | | | | | | | This should remove instances of zero-width sigspecs in the netlist, avoiding problems in the Verilog backend with emitting them. See #3103.
* | sta: very crude static timing analysis passLofty2021-11-252-0/+313
| | | | | | | | Co-authored-by: Eddie Hung <eddie@fpgeh.com>
* | show: Fix wire bit indexing.Marcelina Kościelnicka2021-11-121-3/+16
| | | | | | | | Fixes #3078.

| |
* | logger: Add -check-expected subcommand.Marcelina Kościelnicka2021-08-121-0/+9
| | | | | | | | | | This allows us to have multiple "expect this warning" calls in a single long script, covering only as many passes as necessary.
* | Add v2 memory cells.Marcelina Kościelnicka2021-08-111-1/+1
| |
* | rtlil: Make Process handling more uniform with Cell and Wire.Marcelina Kościelnicka2021-07-122-11/+8
| | | | | | | | | | | | - add a backlink to module from Process - make constructor and destructor protected, expose Module functions to add and remove processes

* | kernel/rtlil: Extract some helpers for checking memory cell types.Marcelina Kościelnicka2021-05-221-1/+1
| | | | | | | | | | | | There will soon be more (versioned) memory cells, so handle passes that only care if a cell is memory-related by a simple helper call instead of a hardcoded list.
* | connect: Add -assert option, fix non-working sigmap.Marcelina Kościelnicka2021-05-081-4/+24
| | | | | | | | Should be useful for writing tests.
* | Clarify bugpoint documentation regarding outputIris Johnson2021-03-241-0/+2
| | | | | | | | | | | | | | Bugpoint's current documentation does specify that the result of a run is stored as the current design, however it's easy to skim over what that means in practice. Add a documentation comment to explain specifically that an after bugpoint `write_xyz` pass is required to save the reduced design.

* | Replace "ILANG" with "RTLIL" everywhere.whitequark2020-08-262-5/+5
|/ | | | | | | | | | 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 typesMarcelina Kościelnicka2020-06-231-1/+4
| | | | | | | | | | | | | | 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).
