VIP for MIPI SPMI

Cadence provides a mature and comprehensive Verification IP (VIP) for the MIPI® SPMIsm (System Power Management Interface) protocol. Incorporating the latest protocol updates, the Cadence® VIP for SPMI provides a complete bus functional model (BFM), integrated automatic protocol checks, and coverage model. Designed for easy integration in testbenches at IP, system-on-chip (SoC), and system levels, the VIP for SPMI helps you reduce time to test, accelerate verification closure, and ensure end-product quality. The VIP runs on all major simulators and supports SystemVerilog and e verification languages along with associated methodologies, including the Universal Verification Methodology (UVM) and Open Verification Methodology (OVM).

Specification Support

The VIP for SPMI supports the following specifications

Protocol Features

The following table describes key features from the specification that are implemented in the VIP.

FEATURE NAME

DESCRIPTION

Topology

Supports multiple slaves and multiple masters topology

Clock

Supports both High Speed and Low Speed device classes

Master Connection

Supports Master Connection by Detection of SSC (Sequence Start Condition), Detection o Bus Idle, Detection of Bus arbitration

Master Arbitration

Supports Master Priority and Secondary arbitration requests

Slave Types

Supports both RCS (Request Capable Slave) and NRCS (Non Request Capable Slave) slaves

Slave Arbitration

Supports A-bit and SR-bit slave arbitration requests

Packet Generation

Supports Command, Address, Data, and No Response Frame generation, supports all SPMI commands

Device Address Types

Supports MID (Master ID), GSID (Group Slave ID), USID (Unique Slave ID) device addresses

ACK/NACK

Supports ACK /NACK mechanism as per version 2.0 specification

Arbitration Generation

Capability to generate simultaneous Arbitration request Scenario

Error Injection

Supports injection/detection of errors for example parity errors/ noise spike at different arbitration level

SSC

Supports generation and detection of SSC (Sequence Start Condition)

Event Notificaiton

 Arbitration win/lost, error detection (e.g., noise spike detection, etc.) command/data/address frame sent, slave A/SR bit eligibility status, etc.

 

Key Verification Capabilities

  • SystemVerilog coverage infrastructure for extendable coverage
