以复位信号的生成为例,由于SC_METHOD和SC_THREAD都是阻塞执行的,即在执行对应的函数时,其他函数无法进行,所以在执行generate_reset()函数时,其他函数暂停,那么在写高电平信号后,遇到wait()后,程序会跳出generate_rest(),转而执行其他函数,当其敏感信号,即时钟信号下降沿到来时,会继续执行上次跳出的位置后的语句,...

The macro HEPSY_P(X)is inserted at the end of the infinite loop body of each SC_THREAD representing a process to count the number of times it has been executed (i.e., the number of loops).As shown in Fig. 6, it simply calls the Profiling() method of SystemManager that updates the...
• multi-channel: this method consists in the use of multiple memory chips [6] controlled in a totally independent manner on dedicated I/O interfaces. The average throughput grows proportionally to the number of channels, but there is also an increase in the logic complexity of the controller...

then comes the run method so run is a standard call back within OVM and it represents behavior is executed during simulation. the System C equivalent of this with just the socket thread process the run method is making a call to b_transport. and this is a standard TLM to naught interface...
