## Overview

This is a SystemVerilog/UVM UART verification IP: engineers run tests that exercise UART configurations and error scenarios against a DUT. The README documents the VIP component roles and the test/sequence coverage, but no source excerpts were available to confirm internal calls or exact wiring; links therefore show only documented verification relationships, not a detailed runtime pipeline.

Main entry points: [`testcases`](https://github.com/thp-tran/uart_vip/tree/master/testcases) (Test cases), [`sequences`](https://github.com/thp-tran/uart_vip/tree/master/sequences) (Sequence suite), [`vip/uart_driver.sv`](https://github.com/thp-tran/uart_vip/blob/master/vip/uart_driver.sv) (Driver), [`rtl/uart_dut.sv`](https://github.com/thp-tran/uart_vip/blob/master/rtl/uart_dut.sv) (UART DUT)
