Armond Posted May 31, 2012 Report Share Posted May 31, 2012 (edited) Does anybody have recommendations on how to work around the fact that a wait_for_grant with lock_request can obtain lock before being granted when relevancy is in play? I am looking to have one sequence (say, sequence 'A') obtain a lock and grant only when relevant, while allowing a separate sequence (say, sequence 'B') to obtain grant in the meantime. Apparently, sequence A can obtain lock but not be granted which chokes out sequence B causing the driver to hang. From uvm_sequencer_base.sv // Task: wait_for_grant // // This task issues a request for the specified sequence. If item_priority // is not specified, then the current sequence priority will be used by the // arbiter. If a lock_request is made, then the sequencer will issue a lock // immediately before granting the sequence. (Note that the lock may be // granted without the sequence being granted if is_relevant is not asserted). // Edited May 31, 2012 by Armond Quote Link to comment Share on other sites More sharing options...
