# UART: loopback

> Test system loopback: enable system loopback, drive uart TX and verify data is loopbacked through RX (RDATA equals WDATA). Test line loopback: enable line loopback, drive uart_rx with random data and verify uart_tx has same value (no synchronizer register between them).

Write a UVM sequence that extends `uart_base_vseq` to verify the above.

**Output:** `/home/dev/workspace/sequences/uart_loopback_vseq.sv` and `/home/dev/workspace/agent_sim_cfg.hjson`

**Run:** `/home/dev/scripts/run_test.sh uart_loopback`
