不同芯片的JTAG协议不尽相同,基于TestBench或者原型验证的方式,在验证JTAG协议上存在着验证效率低下、可移植性差或者无法完全复制芯片的JTAG功能,这对JTAG协议验证调试提出了巨大的挑战。众所周知,通用验证方法学UVM在IC验证领域得到了全面广泛的运用[2-3],其所具有的封装、继承、面向对象等这些优点,并且包含大量功能...
Server:tcl+telnet SW:openocd+JTAG_DPI+VCS仿真(riscvbase+1core+multi_harts) 用tcl,通过telnet连接openocd,与JTAG_DPI连接,JTAG_DPI的verilog model 例化在testbench中,DUT是riscv的core,具有JTAG的调试接口,遵循riscv-debug-spec 使用过程中的简单记录,有理解不对或者有偏差的大家随时私信沟通勘正,谢谢 需要...
#第三,将仿真工具从默认的questa更改为vcs,进行仿真。 run_testbench_simulations -simulator vcs
多数情况下是编写一段既冗长且不易维护的TestBench代码进行验证;有些情况依赖FPGA原型验证手段去验证JTAG协议,但在该情况下,一些模块需进行FPGA资源替换,无法保证与RTL级网表一致,可能导致流片后回来的芯片JTAG调试不通。针对这些情况,结合UVM方法学的通用性和C语言的便利性,提出一种基于UVM和C语言联合验证JTAG调试...
Verification IP for JTAG achieves rapid verification of JTAG based designs (Joint Test Action Group), an industry standard for verifying designs.
从施加激励和检查响应的角度看,Tcl + Virtual JTAG是一种板级的验证平台,就像使用testbench在Modelsim中验证一样。 需要说明的一点是,上面这句话仅仅强调了VJI调试与Modelsim仿真二者在功能上的近似性。除了上面这一点近似性外,调试与仿真的差异还很多,比如运行速度、控制和观察信号的难易程度、开发成本等等。总体来...

First, instantiate the fli_jtag entity in your design (probably an testbench) and drive your JTAG TAP with its signals.-- example: fli_jtag_inst : entity work.fli_jtag port map ( clk => clk, tdo => con_jtag_tdo, tck => con_jtag_tck, tms => con_jtag_tms, tdi => con_jtag_...
