Abstract :
This paper presents the experiences of the Texas Instruments Bus Solutions ASIC design team in its efforts to create and use a component written in VHDL which was embedded into the test environment for an ASIC. The VHDL component described had to be: dynamically controllable; able to accept and check a wide range of expected results from the ASIC design; able to stimulate the design in every action which was compliant with the IrLAP specification; and able to inject several different kinds of errors into the stimulus flow under user control. Embedding this level of stimulus strength, self-checking and user control was a challenge, but completing the component allowed the ASIC design team to field a fully verified interface which has needed no changes since its release to silicon
