Overview

Cadence provides a mature and comprehensive Verification IP (VIP) for the JESD204 protocol. Incorporating the latest protocol updates, the Cadence® Verification IP for JESD204 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 JESD204 helps you reduce time to test, accelerate verification closure, and ensure end-product quality. The VIP runs on all major simulators and supports SystemVerilog verification language along with associated methodologies, including the Universal Verification Methodology (UVM).

JESD204 Frame Mapping explained from converter samples to lanes

The JESD204 Transport Layer oversees converter data mapping onto a set of JESD204 Lanes. The nature of these lanes is dependent on the version of the JESD204 standard and a function of the PCS and over the years despite the Serdes technology changing with ever increasing line rates, the function and features of the Transport Layer remained the same

Multiple ways JESD204 performs bitstream alignment

Bitstream alignment is a function of the Receiver (RX), as seen in the figure below it is the first functional block of the receiver right after the clock domain crossing (CDC) and gear boxing which are quite generic Serdes adaptation layer that can be found in almost every design working with a Serdes.
