Ben Widawsky 999811572a intel_synth: Fix help message 
cyclonev has been a "supported" family since the initial commit. The old
commit message suggested to use a10gx which is incorrect.

Aside from the obvious lack of functional change due to this just being
a help message, users who were previously using "a10gx" for "cyclonev" will
also have no functional change by using "cyclonev" instead.

The help and code default to MAX10 for the family, however the couple of

ice40: Adapt the relut process passes to the new $lut/SB_LUT4 port map
 2019-07-17 07:55:26 +01:00
Sylvain Munaut f28e38de99 ice40: Adapt the relut process passes to the new $lut <=> SB_LUT4 port map 
The new mapping introduced in 437fec0d88
needed matching adaptation when converting and optimizing LUTs during
the relut process

Fixes #1187

whitequark 4ff44d85a5 write_verilog: dump zero width constants correctly. 
Before this commit, zero width constants were dumped as "" (empty
string). Unfortunately, 1364-2005 5.2.3.3 indicates that an empty
string is equivalent to "\0", and is 8 bits wide, so that's wrong.

After this commit, a replication operation with a count of zero is
used instead, which is explicitly permitted per 1364-2005 5.1.14,
and is defined to have size zero. (Its operand has to have a non-zero
size for it to be legal, though.)

Fixes #948 (again).
