When I ran my implementation I could see the program footprint of +about 400K during the whole simulation. +The test runs about 20 seconds and memory footprint grows to about 90MB. If +you run it longer it starts swapping memory do the disk and goes very +slowly. So I waited till it grew to 1GB and then killed it because all +computer does at that point is swapping memory. I guess if you let it run +long enough it would eventually die. I think this happens only with +optimized libraries. +*/ + +//-------------------------------------------------------------------------- + +#include <systemc.h> + +#define sc_ns SC_NS +#define sc_ms SC_MS + +class A : public sc_module +{ + sc_event e1; + + void f() + { + while(true) + { + e1.notify(sc_time(5,sc_ns)); + wait(e1); + + wait(2,sc_ns); + } + } + public: + sc_in_clk clk; + SC_CTOR(A) { SC_THREAD(f); sensitive<<clk;} +}; + +class B : public sc_module +{ + sc_event e2, e3; + void f() + { + while(true) + { + e2.notify(sc_time(1,sc_ns)); + wait(e2); + + e3.notify(sc_time(10,sc_ns)); + + wait(e3); + } + } + public: + sc_in_clk clk; + SC_CTOR(B) { SC_THREAD(f); sensitive<<clk;} +}; + +int sc_main(int argc, char* argv[]) +{ + A a("a"); + B b("b"); + + sc_time clk_time(10.0, sc_ns); + sc_clock clock("clock",clk_time); + a.clk(clock); + b.clk(clock); + + sc_start(0, SC_NS); + sc_time sim_time(10.,sc_ms); + sc_start(sim_time); + return 0; +} +//-------------------------------------------------------------------------- |
