MIPI A-PHY Verification IP

MIPI A-PHY provides an efficient and simple way to verify the MIPI A-PHY. The SmartDV Verification IP for MIPI A-PHY is fully compliant with MIPI A-PHY version upto 2.0 Specification and provides the following features.

MIPI A-PHY Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

MIPI A-PHY Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.

• Implemented in native OpenVera, SystemVerilog, Verilog and SystemC.
• Supported RVM, AVM, VMM, OVM, UVM and non-standard verify env.
• Supports MIPI A-PHY specification version upto 2.0.
• Supports single lane and dual lane, point-to-point and serial communication technology.
• Supports PHY layer and Data link layer features.
• MIPI A-PHY provides a main unidirectional data stream and a bi-directional low- throughput command and control data stream, and can optionally also deliver the required power supply to peripheral units (i.e., the sensors and/or displays at the edge of the network) directly via the A-PHY data line.
• The model has a rich set of configuration parameters to control MIPI A-PHY functionality.
• Support APPI interface between MIPI A-PHY and Native protocol.
• Support multiple high speed gears (Downlink/Reverse Downlink) ranging from 2Gbps up to 32 Gbps.
• Support multiple low speed gears (Uplink) ranging from 100Mbps up to 1600 Mbps.
• Support 7 discrete Downlink Gears: G1, G2, G3, G4, G5, G6 and G7 and 3 discrete Uplink Gears: U1, U2 and U3
• Support two types of profiles :
• Profile 1 (P1-NRZ 8B/10B)
• Profile 2 (P2 -PAM 4, 8 ,16)
• Support clock recovery, Sink Transmitter shall use the recovered Source clock to generate the proper Sink transmit clock, to reach the proper port rate.
• Support Back-to-Back A-Packets 8B/10B Encapsulation
• Support for below Retransmission types
