Top-down system level design methodology using SpecC, VCC and SystemC

In this paper we suggest a top-down methodology from C to silicon. In our methodology, we focus on methods to make the design flow smooth, efficient, and easy. The proposed methodology is a pure top-down methodology. We developed our design methodology by using SpecC, VCC, and SystemC. We choose SpecC, VCC and SystemC because they are all C-related and each have strong support in at least one field of design. Our proposal for a methodology is based on our experiences of attempting to model the JPEG encoder with SpecC, SystemC and VCC, and one internal project, attempting to implement architecture exploration for MPEG encoding and decoding using VCC.
