How do you Verify the AMBA System Level Environment?
In my previous blog, AMBA based Subsystems: What does it take to verify them?, I had discussed some of the key verification challenges when it comes to verifying complex SOCs based on AMBA based subsystems. It was observed that it would indeed be useful to have an extensible AMBA based verification environment which can be tweaked minimally so that it can be reused for new systems or derivatives.
To enable SOC verification engineers to create highly configurable AMBA fabric, the system environment should provide place-holders for hooking the DUT with any of the quintessential AMBA VIP components such as AXI3/4/ACE, AHB or APB. With the use of AMBA System environment we can configure it to instantiate as many number of AXI/AHB/APB VIP with minimal additional code. Thus, such an environment would need to encapsulate the following among others:
