Hi there, I want to simulate a lager system which calculates the inner product of two large vectors. The target vector size is 10^6, but now I can only achieve 4096. When the size N equals 8192, it reports an error: ./../src/systemc/sc_cor_qt.cpp:115: virtual void sc_core::sc_cor_qt::stack_protect(bool): Assertion `ret == 0' failed. I tried set_stack_size which does not work. Because any single thread is not large. They are either an adder or a multiplier. But the whole system is quite large, containing N multiplier and more than N adders. I guess enlarge the stack for sc_main may help, but I do not know how to do that. There is such an option in ModelSim, however, it does not work for my case. Does anybody have any suggestion? Thanks. Jintao
