Transaction based verification is used for faster verification purpose. Reusable transactors are designed and designs are verified at transaction level using these transactors. The test bench are written in higher level language and applied to design via Transactor. Hardware emulators accelerate the use of transaction advantages for the verification people. A number of SoCs and components can be verified with this methodology. The Device under test (DUT) used here is 5th order signed DA-FIR filter and the Transactor designed is AMBA® AHB™ from ARM. The Transactor is designed as Bus functional model in Verilog and state machine model in C++. The C++ based test bench gives the command (input) for verifying design. The Transactor takes care of the signal needed for applying to DUT. The tool used for the verification is Eve’s ZeBu. The verification environment and methodology has been described and compared with the present scenario. Complexity and speed performance are the main constraints for the comparison.
