You can optionally group multiple related DRC checks that can be run together into a DRC rule
deck. To do this, you must first create the DRC rule deck by using the
create_drc_ruledeck
command. Once the DRC rule deck is created,
DRCs can be added and removed from the DRC rule deck by using the
add_drc_checks
and remove_drc_checks
commands.
Mixing user-defined checks and predefined checks into a single DRC rule deck is allowed
in the Vivado Design Suite. Below is an example of creating a DRC rule
deck called myrules
along with the addition and removal of DRCs from
the DRC rule deck.
create_drc_ruledeck myrules
add_drc_checks -ruledeck myrules {RAMW-1 RAMW-2 RAMW-3}
remove_drc_checks {RAMW-2} -ruledeck myrules
Note: If the
is_enabled
property of the DRC is set to FALSE, the DRC does not run as
part of the DRC rule deck when running report_drc
. In
some cases, it might be more desirable to disable the DRC than to remove it from the DRC
rule deck.
