This comment says that Cadence doesn't support OSS:
Cadence is expected to write out a configuration that gives no consideration to
OSS.
Therefore, it is better not to use it on FreeBSD, where the final output
interface to hardware is OSS.
Please support OSS so that it would work properly on *BSD systems.
