Overview

JESD204 Verification IP for your IP, SoC, and system-level design testing.

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).

Supported Specification: JESD204B and JESD204C

Product Highlights

  • Support testbench language interfaces for SystemVerilog, UVM, OVM, e, and SystemC
  • Contains predefined checks to verify that the DUT agents, transmitter and receiver, adhere to the supported protocol features
  • Generates constrained-random bus traffic with predefined error injection
  • Callbacks access at multiple TX and RX queue points for scoreboarding and data manipulation
  • Packet tracker creation for easy debugging of all the transactions on the channels
