System prototypes are hybrid verification solutions that incorporate elements of hardware (including FPGA-based systems), software (virtual) models, and traditional EDA simulators. Bringing these technologies together enables designers to mix and match modeling solutions to get the best out of their resources, and to meet their design and verification needs.
There are two core technologies that underpin most system prototyping solutions and enable them to communicate. Co-simulation typically brings together RTL simulation and hardware at the cycle level. The simulator and hardware work in lock-step and communicate through signal-level links. Design teams use transaction-based communication to connect virtual models and hardware using abstracted messaging.
Figure 149 compares co-simulation, transaction-based verification and in-circuit prototyping in terms of relative performance and autonomy. Linking the prototype to a simulator allows the testbench to control the hardware, but at the expense of reduced performance compared with the free-running prototype.
