2.1. Factors Affecting Compilation Results

Almost any change to the following project settings, hardware, or software can impact the results from one compilation to the next.
  • Project Files—changes to project settings (.qsf, quartus2.ini), design files, and timing constraints (.sdc) can change the results.
  • Any setting that changes the number of processors during compilation can impact compilation results.
  • Hardware—CPU architecture, not including hard disk or memory size differences. Windows XP x32 results are not identical to Windows XP x64 results. Linux x86 results is not identical to Linux x86_64.
  • Quartus® Prime Software Version—including build number and installed interim updates. Click Help > About to obtain this information.
  • Operating System—Windows or Linux operating system, excluding version updates. For example, Windows XP, Windows Vista, and Windows 7 results are identical. Similarly, Linux RHEL, CentOS 4, and CentOS 5 results are identical.
