hello world microblaze system simulation in vivado simulator

[verilog_bee]

Hi,

I am a beginner at Xilinx (Vivado). I am facing some issues in "hello world" SDK simulation in Vivado simulator with very basic MicroBlaze system. I have followed every step of the document "embedded debugging techniques", but unable to see a print of "Hello world" at output console in Vivado simulator.

Attached are some screenshot of Vivado project & simulation waveform & an OBJ dump file as discussed in a document for MicroBlaze.

I also followed some of the threads from Community Forums as mentioned below but not got succeeded :

1.Simulation of Microblaze based system with Vivado simulator.

2. "Hello world" with Microblaze does not display in the console the message "hello world" Nexys ddr4.

Please guide me how I will get the expected output.

Please feel free if any further information required.

Hi @verilog_bee,

Please check this tutorial and hello world simulation with micro blaze:

Greetings,

Thanks for a quick response.

I followed suggested document(https://www.xilinx.com/support/documentation/application_notes/xapp1180.pdf) still hello world is not printed on Tcl console(Vivado simulator).

Generated testbench with command :  tclapp::xilinx::designutils::write_ip_integrator_testbench - verilog -addToProject.

Is there any settings needs to be done in SDK ? 

do we need to initialise uartlite?

Greetings,

During your response time for my post, I have used "base_microblaze" design example where I have seen a testbench that has a UART receiver.

so data sent by UARTLITE CORE captured by this receiver & displayed on TCL console in Vivado simulator. 

do I every time need this receiver for the output of "hello world" in a Viavdo simulator for SDK application simulation ????

Looking for your prompt response.........

Very disappointed due to slow response
