解决方案
1
If the CPLD fitter program hitop runs for too long (over an hour) or if it terminates with a bus error, you may be able to get results more quickly by turning on the new Multi-level Logic Optimization option for the fitter.
To do this in the Flow Engine, go to Setup -> Options. Click on the Edit Template button in the Options dialog. Go to the Advanced Optimization section and select the checkbox marked Multi-Level Logic Optimization.

You can also do it using the -mlopt option for the CPLD script (for Solaris).
