The UART /USART Verification IP provides an effective & efficient way to verify the components interfacing with UART/USART interface of an ASIC/FPGA or SoC. The UART/USART VIP is fully compliant with the Standard National Semiconductor PC16550D specification of UART/USART. This VIP is a light weight with an easy plug-and-play interface so that there is no hit on the design time and the simulation time.
UART/USART Verification IP
Overview
Key Features
- Available in UVM, System UVM, UVM.
- According to the National Semiconductor PC16550D Compliance.
- Supports Simplex and Duplex mode.
- Independently controlled transmit, receive, line status, and data set interrupts
- A programmable baud generator divides any input clock by 1 to (2^16 – 1) and generates baud clock according to the spec.
- Both 16x and 13x sample mode supported.
- Independent receiver clock input.
- Full duplex operation.
- MODEM control functions (CTS, RTS, DSR, DTR, RI and DCD).
- Fully programmable serial-interface.
- 5-, 6-, 7-, or 8-bit characters.
- Even, odd, or no-parity bit generation and detection.
- 1, 1.5 or 2 stop bit generation.
