Merge pull request #2485 from whitequark/cxxrtl-cell-input-buffering 
cxxrtl: don't overwrite buffered inputs
 2020-12-12 19:55:57 +00:00
whitequark e4aa8bc96b cxxrtl: don't overwrite buffered inputs. 
Before this commit, a cell's input was always assigned like:

    p_cell.p_input = (value...);

If `p_input` is buffered (e.g. if the design is built at -O0), this
is not correct. (In practice, this breaks clocking.) Unfortunately,
the incorrect design was compiled without diagnostics because wire<>
was move-assignable and also implicitly constructible from value<>.

After this commit, cell inputs are no longer incorrectly assumed to
always be unbuffered, and wires are not assignable from values.

whitequark aa0a15a42c cxxrtl: use CXXRTL_ASSERT for RTL contract violations instead of assert. 
RTL contract violations and C++ contract violations are different:
the former depend on the netlist and will never violate memory safety
whereas the latter may. When loading a CXXRTL simulation into another
process, RTL contract violations should generally not crash it, while
C++ contract violations should.

Miodrag Milanovic 1c4a18f66f Bump required Verific version 2020-12-02 15:18:04 +01:00
whitequark 5beab5bc17 cxxrtl: provide a way to perform unobtrusive power-on reset. 
Although it is always possible to destroy and recreate the design to
simulate a power-on reset, this has two drawbacks:
  * Black boxes are also destroyed and recreated, which causes them
    to reacquire their resources, which might be costly and/or erase
    important state.
  * Pointers into the design are invalidated and have to be acquired
    again, which is costly and might be very inconvenient if they are
    captured elsewhere (especially through the C API).
