Sylvain Munaut acd9eeef7c ice40: Fix SPRAM model to keep data stable if chipselect is low 
According to the official simulation model, and also cross-checked
on real hardware, the data output of the SPRAM when chipselect is
low is kept stable. It doesn't go undefined.

Alberto Gonzalez 07f0874779 Clean up pseudo-private member usage in `backends/smt2/smt2.cc`. 2020-03-13 21:49:12 +00:00
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.

Improve ABC repository management in Makefile 
`rev-parse --short` output may have a different abbreviated hash length than
ABCREV, so a simple string comparison always fails, even if the correct
commit is checked out. Pass both commits through rev-parse and then
compare the full hashes instead.

Add an `echo-abc-rev` target so that packaging scripts can set ABCPULL=0 and
handle all the git nastiness themselves.

Marcus Comstedt 5e94bf0291 refixed parsing of constant with comment between size and value 
The three parts of a based constant (size, base, digits) are now three
separate tokens, allowing the linear whitespace (including comments)
between them to be treated as normal inter-token whitespace.
