Overview

Best-in-class UART Verification IP for your IP, SoC and system-level design testing.

Best-in-class UART Verification IP for your IP, SoC and system-level design testing. In production since 2014 on dozens of production designs.

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

Supported Specification: Standard UART 16550 Specification

Product Highlights

  • Supports testbench language interfaces for SystemVerilog and UVM.
  • Compliance: Contains predefined checks to verify that the DUT agents adhere to the protocol rules defined in the UART specification
  • Dynamic activation allows to defer the choice of which instances are active until simulation actually begins
  • Extensive callbacks support for TX/RX packets to enable score-boarding and data manipulation
  • Basic SystemVerilog coverage support
  • Packet tracker creation for easy debugging
