|\ | | | | icetime: Add support for searching for chipdb relative to binary
| * icetime: Add support for searching for chipdb relative to binaryNathan Rossi2018-09-033-25/+190
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Like yosys and arachne-pnr, allow for searching for the desired chipdb file relative to the executing binaries directory. This allows for portable builds of icetime without needing to specify the exact path to the needed chipdb file with the -C arg. In order to support this icetime must be able to get the "proc_self_dirname" path just like yosys and arachne-pnr. As such copy the equivalent code to get this path information. To avoid cluttering the icetime.cc file with this code, place it in a separate iceutil.cc file. Signed-off-by: Nathan Rossi <nathan@nathanrossi.com>

* 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.
