Due to a problem in the Intel® Quartus® Prime Pro Edition software version 20.2 and earlier, you may see the compile time is unexpectedly long for designs targeting Intel® Stratix® 10 devices. This is because of some slow rule checkers in the Design Assistant and the Design Assistant flow is enabled by default.
To work around this problem, disable the DA flow:
- Check off "Enable Design Assistant execution during compilation" in Settings -> Design Assistant Rule Settings or
- Write the following QSF assignment in your project's QSF:
set_global_assignment -name FLOW_ENABLE_DESIGN_ASSISTANT ON
This problem is fixed starting with the Intel® Quartus® Prime Pro Edition software version 20.3.
