93d8ef9663 Fixed bigtest 
Accidentally broke it in cc27d27 (this is why regular testing is important).

b2d0368e26 Testing fifo things in CI 
Turns out the bigtest golden ref is failing a_count_diff, need to fix that before removing the default statement.

Base example code is fine.  New shell script to run default case and then nofullskip.
Expects returncode=2 after running nofullskip.

cc27d27c05 More literalincludes 
Tidying up of newstart.rst and fifo.sv to include as much code as possible by reference.
Should reduce repetition and make it easier if changes occur in source.

907db48ac9 Updating from feedback 
Primarily addressing Nak's comments on the PR first.
Of note is the change from separate files to a single file.
Changed to boolector engine and bmc by default.
Updated install instructions to move z3 to optional and boolector to
recommended.
Literal code includes use :lines: option.

499371fd39 Use the test Makefile for all examples 
* Rename and move sbysrc/demo[123].sby to docs/examples/demos
    * Make them use multiple tasks for multiple engines
* Scan docs/examples for sby files for make test
* `make ci` is now `NOSKIP` by default
* Skip scripts using `verific` w/o yosys verific support
    * This does not fail even with NOSKIP set

fedfae0e9c examples: Fix use of SVA value change expressions 
The $stable value change expression cannot be true for a non-x signal in
the initial state. This is now correctly handled by the verific import,
so the dpmem example needs to start assuming `$stable` only after
leaving the initial state.
