Voltage Identification (VID)

Intel processors/chipsets are individually calibrated in the factory to operate on a

specific voltage/frequency and operating-condition curve specified for that individual

processor. In normal operation, the processor autonomously issues voltage control

requests according to this calibrated curve using the serial voltage-identifier (SVID)

interface. Altering the voltage applied at the processor/chipset causing operation

outside of this calibrated curve is considered out-of-specification operation.

The SVID bus consists of three open-drain signals: clock, data, and alert# to both set

voltage-levels and gather telemetry data from the voltage regulators. Voltages are

controlled per an 8-bit integer value, called a VID, that maps to an analog voltage

level. An offset field also exists that allows altering the VID table. Alert can be used to

inform the processor that a voltage-change request has been completed or to

interrupt the processor with a fault notification.

For VID coding and further information, refer to the IMVP9.1 (FVM feature support

version) PWM Specification and Serial VID (SVID) Protocol Specification .

Fast V-Mode

An SoC integrated detector monitors when the SoC load current exceeds a preset

threshold by monitoring for SoC voltage domain voltage droop. The SoC compares the

IMVP VR output voltage with a preset threshold voltage (Vtrip) and when the IMVP VR

output voltage reached this Vtrip, the SoC throttles itself to reduce the SoC load

current.

IMVP9.1 VRs enhance this detector by adding a cycle-by-cycle current limiting feature

where the IMVP VR quickly enters cycle by cycle current limit (becomes a current

source) with the VR output current limited to a preset value (I TRIP ) as set in the VR

ICC_limit register

Terminology

1. IccMax is the maximum current the processor can draw, typically seen running a

virus application (stress applications specifically designed to push the SoC to

maximum power). This is the current used to design the voltage regulator

decoupling.

2. PMax (PL4) is the maximum instantaneous electrical power drawn by the SoC

(per power rail), typically seen running a virus app (stress applications specifically

designed to reach maximum consumed power) with an all core turbo and Tjmax

scenario.

3. IccMax.app is less than IccMax and is the electrical current drawn by the SoC

(per power rail) while running a typical user realistic application(s) scenario at

P0nmax and Tjmax. It corresponds to PMax.App.

4. PMax.App (PL4.App) is less than PMax and is the power drawn by the SoC (per

power rail) while running a typical user realistic application(s) scenario at P0nmax

and Tjmax. It corresponds to IccMax.App.

5. I

TRIP

is VR output current limit threshold above which the VR goes into current

limit. This current is greater than IccMax.App and less than IccMax. It is

determined by customer-specific VR current capability and the VR IMON

measurement tolerance (TOL IMON).

Generally, I

TRIP

= IccMax.App/(1-TOLI MON ). Setting I

TRIP

this way guarantees

the VR never goes into current limit below IccMax.APP.

6. I

TRIPMax

is the peak current the VR FETs and inductors could see accounting for

the VR controller current measurement tolerance (TOL IMON ). The SoC VR and

system input power sources must be able to sustain this current for at least 10ms.

NOTE

TOL_IMON can be sometimes called as ITRIP_TOL or ITRIP_ACCURACY

7. V

TRIP

is the output voltage level below which the SoC will self-throttle. In

application, this voltage is internally set in the SoC and is not visible external to

the SoC. For the purposes of VRTT testing, a Vtrip will be provided for use with the

Python* test script used for FVM testing

Benefits

• The SoC droop detector and IMVP cycle by cycle limiting work together to allow

the voltage regulator inductors and FETs to be sized for realistic workload current

(~ICCMAX.APP) instead of virus currents (ICCMAX)

• Allows power sources to be sized for realistic workload currents, by shielding them

from SoC large dynamic loading events that occur when the SoC current exceeds

the worst case realistic maximum current (ICCMAX.APP).

Current Excursion Protection (CEP)

This power management is a Processor integrated detector that senses when the

Processor load current exceeds a preset threshold by monitoring for a Processor power

domain voltage droop at the Processor power domain IMVPVR sense point. The

Processor compares the IMVPVR output voltage with a preset threshold voltage (V

TRIP

)

and when the IMVPVR output voltage is equal to or less than V

TRIP

, the Processor

internally throttles itself to reduce the Processor load current and the power

• ICCMAX is the maximum current processor can draw, typically seen running a

virus application (stress applications specifically designed to push the SoC to

With Fast Vmode enabled, output decoupling would see this ICCMax current.

Output decoupling would need to be able to take transient load step up to this
