A first block, a second block, a shared memory, and a third block are generated in a circuit design in response to user input control. The first block is coupled to the second block, the second block is coupled to the shared memory, and the shared memory is coupled to the third block in response to user...http://www.google.com.tw/patents/US7343572?utm_source=gb-gplus-share專利 US7343572 - Vector interface to shared memory in simulating a circuit design
