whitequark 3b5a1314cd cxxrtl: rename "elision" to "inlining". NFC. 
"Elision" in this context is an unusual and not very descriptive term
whereas "inlining" is common and straightforward. Also, introducing
"inlining" makes it easier to introduce its dual under the obvious
name "outlining".

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).
