Hello, Inside uvm_reg there is a semaphore called m_atomic. This semaphore protect from write/read from several registers at the same time. I have a sequence that sends an item with write_reg task. When this sequence is being called several times (different instances) while the write aceess was not finished I can't see the item of the new sequence untill the first one is finished. I would like to stop the transaction sometimes when the new sequence arrives. How can I do this? Thanks
