C-Elegans e395b74799 Update PLL DIVF range to be [0,127] 
As discussed in issue #83, the range of the DIVF parameter in the
iCE40 PLL Usage Guide is incorrectly listed as being 0-63, when it
should actually be 0-127 when used in the SIMPLE feedback mode. This
however does apply in other feedback modes, where the DIVF range should
still be restricted to 0-63

Clifford Wolf 8611d612d4 Merge pull request #81 from cbiffle/allow-long-sym-lines 
icetime: allow longer lines in input asc files
 2017-05-11 11:06:27 +02:00
Cliff L. Biffle e787fa2d30 icetime: never silently truncate asc file lines 
icetime was reading the asc configuration file using a 128-byte line
buffer -- which is usually fine, but can cause it to truncate the names
of nets given in .sym lines if those names are very, very long.  The way
fgets was being used meant this went undetected.

Long net names like this can arise in deeply hierarchical designs,
particularly if there's a code generator involved.

This change:
1. Increases the buffer size to 64kiB.
2. Adds a truncation check that causes icetime to fail.

A more robust solution would manage the line buffer on the heap, since
the symbol gets copied into a std::string anyway, but this is a
workaround for now.
