@User And again, the riscv core in caravel was placed and routed using the open source tools not the closed source ones

Yes, I suppose I assume commercial when I think 'not acessible for submission'. Closed source is a better term. I'm very surprised with the RISCV core, the cell density exceeds what could be done in MPW1 without extensive manual or scripted placement.
Must have been my design could net be routed at high density?

@Jean: Ahmed Ghazy was working several steps ahead on the management SoC core. There was always the problem of doing things ourselves and then communicating that to everyone else. I was also disappointed with the early results of openlane.
