ID:20031 Parallel compilation is enabled for <num_procs_used> processors, but there are only <num_procs_detected> processors in the system. Runtime may increase due to over usage of the processor space.

CAUSE: Parallel compilation is enabled for the specified number of processors, but there are only specified number of processors available in the system. There may be a risk of runtime increase due to over usage of the processor space.

ACTION: No action is required. Avoid the risk of runtime increase by reducing the number of processors that you have manually specified to the correct number of processors, or allow the Quartus Prime software to automatically choose the number of processors.
