    Not sure if this topic is active. Here is some feedback. 1. Decouple the datatypes library from other core SystemC libraries. In other words it should be a light stand-alone library of its own. 2. Single unified bit vector library for all widths (like ac_int<W>). However having the range function for behavioral modeling (not synthesis) is also very useful. Currently we use the following c++-11 feature: /*----------------------------------------------------------------*/ // This uses a neat template alias trick introduced in C++-11 // to hide the underlying type of either a biguint or _bits_ull // inside a bv. This allows uniform use of bv<W> in the code // while hiding the underlying type // Refer to: Stroustrop's C++11 FAQ /*----------------------------------------------------------------*/ template<bool,int W> struct bv_traits { typedef biguint<W> type; }; template<int W> struct bv_traits<true,W> { typedef _bits_ull<W> type; }; template<int W> using bv = typename bv_traits<W<=64,W>::type; 3. Illegal shifts are a problem. Introduced an artificial layer with static assertion (C++-11) checks to mitigate the problem. Example of static assertion for illegal widths below. There are lots and lots of static and run-rime assertions like this. template <int W> class _bits_ull : public sc_uint_base { public: static const int width = W; enum { valid_ull_width = (W <= 64) }; enum { MAX_WIDTH = 64 // fits into unsigned long long }; // constructors _bits_ull() : sc_uint_base(W) { (void)cmn_static_assert<valid_ull_width>::Invalid_bits_ull_width; } 4. Speed of execution of bit-vectors is critical. I worked with Andy Goodrich to have a faster implementation of sc_biguint<W> and have it locally as a branch to 2.3.0. It does not seem to have made it into the latest standard (v2.3.3). This provides a dramatic improvement in speed. There are other things which can be done to speed it up further. 5. Recently I did some work on concurrency from within the SystemC simulation. Much to my surprise, I find the SystemC datatypes (range functions and the operator[int]) are not thread-safe. This is because of static variables and sc_vpool (sc_temporary) use. Here is an example which on the surface should work fine but has data_races. Note that we can have thread safety issues from either within or outside the SystemC simulation. Races can be found by clang++ thread sanitizer -fsanitize=thread data_race.cc #include <thread> #include <future> #include <systemc> using namespace sc_core; using namespace sc_dt; using namespace std; void thread_func() { sc_uint<32> b32; for (int i = 1; i < 32; i++) { b32[i] = 1; // RACE inside here b32.range(i, i-1) = 2; // RACE inside here } } std::vector<std::future<void>> futures; int main(int argc, char** argv) { const int N_THREADS = 2; for (int i = 0; i < N_THREADS; ++i) { auto f = std::async(std::launch::async, thread_func); futures.push_back(std::move(f)); } return 0; }

/projects/ntsw-arch-public/tools/systemc-22sep2015/systemc-2.3.0/x86_64-gcc8/include/sysc/utils/sc_temporary.h:187:23 in sc_core::sc_vpool<sc_dt::sc_uint_subref>::allocate() ================== ThreadSanitizer: reported 2 warnings 6. A common pattern is to use a fixed width slice of a bit-vector (both set and get). This should be optimized to take advantage of compile time templated left and right (L,R) parameters. For example: template< int W > class biguint { public: ... template<int L, int R, int W2> void set_fslc (const biguint<W2> &b); template<int L, int R> biguint<L - R + 1> fslc () const; } There are other interesting problems to solve as well but don't want to make this post too long.
