Does the openlane flow support static timing analysis on multiple/independent clocks? It seems like only
CLOCK_PERIOD
,
CLOCK_PORT
, and
CLOCK_NET
from the
config.tcl
are honored and the
SDC_FILE
does nothing. I tried to create multiple clocks in the
SDC_FILE
, but only the single clock referenced in the
config.tcl
were analyzed. Can you specify multiple clocks in the
config.tcl
file?

OpenSTA does support multiple clocks. I'm not sure how that is exposed in the openlane flow.
