C-Cubed™

The C-Cubed behavioral synthesizer

The C-Cubed synthesizer is based on formal methods and includes the frontend (compiler) and the backend (HLS system). Currently there are ANSI-C and ADA frontends. More frontends (i.e UML) are expected in the immediate future. The backend synthesizer produces automatically cycle-accurate and fully synthesizable RTL VHDL or Verilog, depending on the choice of the user. More backend languages are expected in the immediate future such as System-C and cycle accurate C.
The whole C-Cubed product chain is based on formal methods, so the generated implementations are first-time-right and provably-correct in regard to the functionality of the input code. The design flow is shown in the figure.
Our customers don’t need to spend months or years in repetitive RTL and netlist verification cycles. With the formal nature of the C-Cubed synthesizer, only rapid compile-and-execute-based verification of the high-level behavioral program code is needed to correct functional bugs.
The backend synthesizer is driven by interface parameters, and resource constraints, so that mapping on any rich (ASIC) or economic (FPGA) technology becomes reality in matter of hours.
