Problem nedir?

Signals between a hardware IP and the parent system design are incorrectly connected causing security risks.

Genişletilmiş açıklama

Individual hardware IP must communicate with the parent system in order for the product to function correctly and as intended. If implemented incorrectly, while not causing any apparent functional issues, may cause security issues. For example, if the IP should only be reset by a system-wide hard reset, but instead the reset input is connected to a software-triggered debug mode reset (which is also asserted during a hard reset), integrity of data inside the IP can be violated.

Detay
System-level verification may be used to ensure that components are correctly connected and that design security requirements are not violated due to interactions between various IP blocks.
