Note:
•
The thermal diode can only be used when the GPU is powered; for example, it
cannot be used when in D3 cold. The 3.3-V supply has to be active for
temperature sensing to work because of the ESD protection diodes.
•
The ideality factor of the on-die thermal diode varies significantly with
temperature and sourcing current. If a design chooses to use the on die thermal
diode of the GPU coupled with an external thermal sensor chip to read the GPU
temperature, the external thermal sensor chip must support and enable beta
compensation.
2.11 Logo Compliance
This product complies with the Windows Logo Program requirements for all target
operating systems. This includes both the current logo and future (draft)
requirements that will be enforced during the lifespan of the product.
2.12 Test Capability Features
"Vega 10" has a variety of test modes and capabilities that provide a high-fault
coverage and low-DPM (defect per million) ratio. It provides the following features
which are implemented in the SOC:
•
Full-scan implementation on the digital core logic which provides high-fault
coverage through ATPG (automatic test-pattern generation) vectors, covers
both the stuck-at and at-speed transition fault.
•
Dedicated test logic (MBIST) for the on-chip memory macros to provide
complete coverage on these modules.
•
JTAG (Joint Test Action Group) test mode, fully compliant with the IEEE.
•
1149.1 standard to support test access interface and board-level connectivity
test.
•
Integrated hardware-diagnostic tests performed automatically upon
initialization.
•
Test Data Register configuration mechanism to support SCAN/MBIST and other
chip-level test functions.
•
Supports analog Macro at-speed loopback test to cover parts which are not
covered by scan/MBIST.
•
Improved access to analog Macro and PLLs to allow full evaluation and
characterization of these modules.
•
Integrated hardware-diagnostic tests performed automatically upon
initialization.
•
Scan register value dump out under security state control.
2.13 Other Features
•
Support for serial-ROM video BIOS.
•
Support for 32- and 64-bit operating systems based on Intel, AMD, and PowerPC
CPUs.
