How to open and read TEXT file in systemC

[Arjun_07]

Hello Everyone,

I am trying to open text file, file is opening but when i am trying to read data in C[MEM_DEPTH] buffer,

nothing is copied from the file, when i am printing the C[MEM_DEPTH] only initialize value =0 is printing.

The task is to read data from file into the buff_1[MEM_DEPTH], then this will be send to source file for writing into the memory.

i am attaching my testbench and text file .

please let me know where i am making a mistake.

Thanks and Regards

Arjun

AFAICS you don't increment the index i in the while loop.

But your code is way to complex.:

	std::ifstream ifs("TEXT.txt");
	if(ifs.is_open()){
		int buf = 0;
		for (int i = 0; i < MEM_DEPTH; i++) {
			ifs >> buf;
			buff_1[i]=buf
		}
	}
	ifs.close();

should replace everything from fopen() until fclose(). And you should avoid using macros, they will bite you. '#define MEM_DEPTH 20' should become 'const size_t MEM_DEPTH=20;'.

You might want to add an else clause and issue an error message in case the file does not open successfully (e.g. due to the filename or location being wrong or permissions). I/O errors always bite when you least expect them and they often waste time figuring out what happened. Clear error messages are very helpful.
