| | | | | | | | | | | | | | | | | | | | | | | | 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

|\ | | | | icetime: allow longer lines in input asc files
| * icetime: never silently truncate asc file linesCliff L. Biffle2017-05-091-2/+10
|/ | | | | | | | | | | | | | | | | | 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.
