所附testbench的代码中将UART的输入和输出相连形成回环测试,先用CPU控制UART输出一个随机数据,然后回环到UART的输入,再用CPU读出来,将输出数据和读出的数据进行自动比对。代码中的CPU的读写操作和自动比对操作都必须定义成任务,不能定义成函数,因为任务是要花费仿真时间的。 这样子的testbench在实际工程中很常用,因为...
2.仿真波形 通过上述testbench仿真的波形如下图1所示,其中前200us为写发送,发送的数据和testbench中的一致,数据和地址是分两次发送的;后200us为读发送,只发送了一次8bits数据,最后在read_valid有效时,对应的read_data与设计的值一致。 图1.uart写发送和读发送仿真波形 好啦!本期uart协议与Verilog实现到此结束啦!

GitHub repository:https://github.com/alexforencich/verilog-uart Introduction This is a basic UART to AXI Stream IP core, written in Verilog with cocotb testbenches. Documentation The main code for the core exists in the rtl subdirectory. The uart_rx.v and uart_tx.v files are the actual ...
UART Assertion IP provides an efficient and smart way to verify the UART designs quickly without a testbench. The SmartDV's UART Assertion IP is fully compliant with standard UART Specification and provides the following features. UART Assertion IP is supported natively inSystemVerilog, VMM, RVM,...
You have the freedom to build your testbench using any of these verification languages: SystemVerilog, e, Verilog, VHDL, or C/C++. Simulation VIP supports the Universal Verification Methodology (UVM) as well as legacy methodologies. Product Highlights - Compatible with industry-standard UART ...
Hi. i have one design that is UART written in verilog code. The simulation is successfully done. However, when i program my design to the DE2 board and connect it to the PC using the RS232, there is no output shown in hyper terminal. i would like to ask a favor that help me to...
一旦定义了这些关系和属性,就需要在SystemVerilog接口中混合使用SVA和covergroup语法来实现它们。这里描述了一个协议监视器示例。 协议监视器的源代码可在此处下载: (在线下载源代码示例,网址为https://verificationacademy.com/cookbook/code-examples). 2 APB3协议测试计划 在验证计划步骤中,应创建一个测试计划,其中列...
