* | aiger: Add yosys-witness support | Jannis Harder | 2022-08-16 | 1 | -0/+3 |
| | | | | | Adds a new json based aiger map file and yosys-witness converters to us this to convert between native and AIGER witness files. | ||||
* | smtbmc: Add native json based witness format + smt2 backend support | Jannis Harder | 2022-08-16 | 1 | -0/+4 |
| | | | | | | | | | | | | | | | | | | | | This adds a native json based witness trace format. By having a common format that includes everything we support, and providing a conversion utility (yosys-witness) we no longer need to implement every format for every tool that deals with witness traces, avoiding a quadratic opportunity to introduce subtle bugs. Included: * smt2: New yosys-smt2-witness info lines containing full hierarchical paths without lossy escaping. * yosys-smtbmc --dump-yw trace.yw: Dump results in the new format. * yosys-smtbmc --yw trace.yw: Read new format as constraints. * yosys-witness: New tool to convert witness formats. Currently this can only display traces in a human-readable-only format and do a passthrough read/write of the new format. * ywio.py: Small python lib for reading and writing the new format. Used by yosys-smtbmc and yosys-witness to avoid duplication. | ||||
* | memory_map: Add -formal option | Jannis Harder | 2022-08-16 | 1 | -0/+1 |
| | | | | | | This maps memories for a global clock based formal verification flow. This implies -keepdc, uses $ff cells for ROMs and sets hdlname attributes. | ||||
* | Add the $anyinit cell and the formalff pass | Jannis Harder | 2022-08-16 | 1 | -0/+6 |
| | | | | | | | These can be used to protect undefined flip-flop initialization values from optimizations that are not sound for formal verification and can help mapping all solver-provided values in witness traces for flows that use different backends simultaneously. | ||||

* | verilog: fix size and signedness of array querying functions | Jannis Harder | 2022-05-30 | 1 | -0/+2 |
| | | | | | | | | | | genrtlil.cc and simplify.cc had inconsistent and slightly broken handling of signedness for array querying functions. These functions are defined to return a signed result. Simplify always produced an unsigned and genrtlil always a signed 32-bit result ignoring the context. Includes tests for the the relvant edge cases for context dependent conversions. | ||||

* | sv: auto add nosync to certain always_comb local vars | Zachary Snow | 2022-01-07 | 1 | -0/+3 |
