    Sir i have an doubt that when i compile any code in system c it generate simv file and i simulate it by using ./simv command but then i wrote new code and complie it , it got compiled the previous code and and showing the same output as previous one. Also in my systemc directory location it generate /csrs directory and inside csrc it generate /sysc directory and inside this it automatically generate .o and .a extention file. Sir could you please advice me on this and guide me that how I will get clear view about systemc. /home/avnita/Workspace/SYSTEM_C_FILES/csrc/sysc/half_adder.o: In function `sc_main': half_adder.cpp:(.text+0x0): multiple definition of `sc_main' /home/avnita/Workspace/SYSTEM_C_FILES/csrc/sysc/and_gate1.o:and_gate1.cpp:(.text+0x0): first defined here collect2: error: ld returned 1 exit status make: *** [product_timestamp] Error 1

    Hiiiii.........I wrote simple and gate code in system c and i am using vcs tool. could you please advice me that how do i complie this code, i follow these step to compile system c code on my tool: 1. syscan filename.cpp 2. vcs -sysc filename.cpp 3. ./simv #include "systemc.h" SC_MODULE(and_a) { sc_in < sc_uint <8> > a, b; sc_out < sc_uint <8> > f; sc_in <bool> clk; void comp_and() { f.write(a.read() & b.read()); } SC_CTOR(and_a) { SC_METHOD( comp_and ); sensitive << a << b; } }; After compilation i got this error message: Parsing design file 'csrc/sysc/simv/top.v' Top Level Modules: sYsTeMcToP sc_main TimeScale is 1 ns / 1 ps Starting vcs inline pass... 2 modules and 0 UDP read.
