Dose wait fork wait until all processes are over ? 为了了解它在这种情况下的行为,让我们在forked two threads 并等待 forked 完成。 moduletb_top;initialbegin// Fork off 3 sub-threads in parallel and the currently executing main threa
moduletb_top;initialbegin#1$display("[%0t ns] Start fork ...",$time);// Main Process: Fork these processes in parallel and wait untill all of them finishfork// Thread1 : Print this statement after 5ns from start of fork#5$display("[%0t ns] Thread1: Orange is named after orange...

wait fork会阻塞调用它的进程,直到该进程启动的所有fork子进程都完成。这些子进程可以是使用fork...join、fork...join_any或fork...join_none创建的。重要的是要注意,wait fork只等待直接由调用进程启动的子进程,而不会等待这些子进程进一步启动的子进程。
SystemVerilog Semaphore Semaphore is just like a bucket with a fixed number of keys. Processes that use a semaphore must first get a key from the bucket before they can continue to execute. Other proceses must wait until keys are available in the bucket for them to use. In a sense, ...
wait(): 等待事件的出发(await),如果事件已经触发,立即返回 clear(): 清楚以触发的事件 is_set(): 判断事件是否触发 旗语 cocotb中提供了Lock操作用来实现与SystemVerilog中相似的操作,不过Lock不可声明旗语为多个: class cocotb.triggers.Lock(name=None) ...
Another thing is that wildcard import statement import pkg::*; doesn't import any identifiers (just make them candidates for import) until there is an explicit reference to that identifier. In addition to import, we can also export a package: By default, declarations imported into a package ...
