Long Placement Optimization Time

My current project's placement optimization phase is long (more than 20 hours).

Is there a way to speed this up by using more CPU cores? I noticed Quartus (v24.1) is configured to use only 25% of my CPU cores, even though I selected to use all cores under the "Parallel Compilation" setting.

    What's your target device? What are your computer specs? How full is the design? Have you enabled any compilation options that will naturally take much longer, like aggressive performance or individual options in the advanced Fitter settings like increasing the placement effort and others?

  • Hi there, is there any updates on this? you may check the optimization results in dashboard report to check if there is too many logic optimized away.
