UART VIP 2017-07-20T06:34:15+00:00

UART VIP (Verification IP) The UART VIP (Universal Asynchronous Receiver/Transmitter) is a highly flexible and configurable verification IP that can be easily integrated into any SOC verification environment. Supporting UVM, this UART VIP is part of the asureVIP portfolio of implementation-proven VIP offerings.

The UART VIP master supports UART and UART16550 modes and was used in successfully verifying a DUT and later silicon proven. The VIP comes with a Bus Monitor that performs protocol checks and reports errors for non compliance with National Semiconductors UART Specification.

Customers using the asureVIP products do so with the confidence of knowing that they have been independently developed by T&VS and successfully deployed by leading SoC companies around the world.

T&VS can also offer asureVIP customers an independent hardware verification service (asureVERIF) that not only reduces development costs and time-to-to-market, but also improves product quality.


  • Compliance: National Semiconductor PC16550D
  • Language: System Verilog
  • Methodology: UVM 1.1
  • Simulators: Cadence Incisive, Mentor Questa, Aldec Riviera-PRO
