Simulation VIP for MIPI SoundWire-I3S

Hot-Join

• Supports configuration-based Hot-Join to wake required PHY without going through ColdStart sequence

LC-PHY

Strength Driving

• Manager and peripheral supports driving and identifying different drive strengths (weak, strong, supply) modeled as Verilog net strengths

CDS and Command Transport Protocol

Phases

• Manager and peripheral support GetStatus, Announce, Write, ReadSetup, ReadData, and Commit phases

• Supports remote read/writes

Codeword Endianness

• Supports codeword transmission and reception in Little and Big endian mode

Stream Synchronization Point

• Supports scheduling SSCR/SSPA commands to align commit point with SSP and notifying commit event

Clock-Config

• Supports dynamic clock config

Transport and Protocol Errors

• Manager and peripheral support injecting and detecting transport errors (bad 8b-10b symbols, bad robust token, bad opcode, bad CRC etc...) and protocol errors

Payload Transport

• Supports up to 32 Manager or Peripheral data ports and up to 16 channels per data port

• Each data port can be programmed to control payload transport pattern

Data Port Sequences of Operation

• Supports all Data Port sequences of operation (start_stream, Insta_start_stream, stop_stream, pause_stream etc.)

FBCSE PHY

• Supports both PHY1/PHY2

• Supports NRZS encoding of CDS

• Clock/data setup and hold time can be controlled

• Supports Clock pause feature

• Supports bus keeper with weak drive strength and special drive

DLV PHY

Clock and Data Recovery

• Peripheral can lock to row syncs to generate CDR clock required for DLV PHY

• Supports bus keeper with weak drive strength and special drive

Registers

• Supports SWI3S-defined registers

• SWI3S-defined Register space can be accessed through frontdoor (using SWI3S Read/Write commands) or backdoor

Phy Control Register

• Register to control PHY behavior

Data Port Registers

• Registers to control Data Port configurations (ReadyCh, SampleWidth, SampleGrouping, PortDirection, etc.)

CDS Transport Registers

• Registers to configure Control Data Stream transport parameters (CDS_Hstart, CDS_DriveType, CDS_Width, etc.) 

Transport and Protocol Errors

• Manager and peripheral support injecting and detecting transport errors (bad 8b-10b symbols, bad robust token, bad opcode, bad CRC, etc.) and protocol errors

• Support to modify CDS from callback to inject any type of error in it
