While these accelerators run very fast, they still run orders of magnitudes slower than real hardware systems. Even tests that use a small amount of “real-time” data can take hours or days to run. Some designers have slowed their real hardware environment to allow connection to the real hardware. This lets the designer use “real stimulus” for some tests. The designer will still typically need to run with a testbench to cover corner cases. 3 summarizes the differences in the verification methods discussed to date.

CHAPTER 4 44 It is possible, however, to set up a condition where the simulation input stimulus activates a design error that does not propagate to an observable output port. In these cases, the first condition cited above applies; however, the second condition is absent. Note that addressing the observability challenge within simulation-based methodology is analogous to solving an automatic test pattern generation (ATPG) problem. That is, ATPG consists of the following steps (see Fig. 3): 1. Enumerate a fault.

Their biggest drawback is slow runtime. HDL software simulators typically cannot be interconnected to real hardware environments because the simulation speed is too slow. The simulated model is effectively data that are being executed by the simulator on the host computer, so there are no “device pins” to connect to the external environment. For small designs, designers can think of and generate test cases for the most important scenarios to test. As the design increases in size, this process becomes increasingly difficult.
