Description

When first run `make prog`, it will take a long time (about 6~7 mins) to finish synthesis, place&route, etc. I find out that during this process, only one CPU core is used, leaving other 7 cores idle. My question is can we add some parameters to let all CPUs run during `make prog`?
My working environment is VM Ubuntu 18.04, 10G RAM, 8 CPU cores.
