Sahand Kashani ac388859e3 Remove dependency on ilang backend since we no longer use it 2020-04-08 23:59:22 +02:00
Sahand Kashani 9edf8869c1 Merge branch 'master' of github.com:YosysHQ/yosys into firrtl_backend_fileinfo 2020-04-08 23:50:37 +02:00
Sahand Kashani 820e3d1dad Remove unnecessary pruning of double-quoting 
In the past I was calling the ILANG_BACKEND::dump_const() to dump
values to an output stream. When these values were strings, the
function used to add quotes around them. The firrtl compiler, in turn,
escaped these quotes and the result was double-quoted strings which
were hard to read.

However I'm now calling design_entity->get_src_attribute() directly
and there is no additional quote being put around it, so we can
safely remove the unnecessary call to str.erase() here.

Sahand Kashani 21492914a2 Strip quotes around fileinfo strings 
Yosys puts quotes around the string that represents the fileinfo whereas
firrtl does not. So when firrtl sees quotes, it escapes them with an extra
backslash which makes it hard to read afterwards.

Alberto Gonzalez 0fda8308bc Add support for optimizing exists-forall problems. 
Modifies smt2 backend to recognize `$anyconst` etc. assigned to a wire with the `maximize` or `minimize` attribute and emit `; yosys-smt2-maximize` or `; yosys-smt2-minimize` directives as appropriate.
Modifies `backends/smt2/smtbmc.py` and `smtio.py` to recognize those directives and emit a `(maximize ...)` or `(minimize ...)` command at the end of `smt_forall_assert()`, as described in the paper "νZ - An Optimizing SMT Solver" by Nikolaj Bjørner et al.
Adds an example `examples/smtbmc/demo9.v` to show how it can be used.
