This readme provides information about the simulation environment for the cl_hello_world example. For more details about overall HDK simulation environment and CL bringup in simulation please refer to RTL_Simulating_CL_Designs

Hello World CL Example Simulation

The test can be run from the verif/scripts directory with all supported simulators:

    $ make TEST=test_hello_world (Runs with XSIM by default)
    $ make TEST=test_hello_world IES=1
    $ make TEST=test_hello_world VCS=1
    $ make TEST=test_hello_world QUESTA=1

The HW/SW co-simulation test can be run from the verif/scripts directory with all supported simulators:

    $ make C_TEST=test_hello_world (Runs with XSIM by default)
    $ make C_TEST=test_hello_world VCS=1
    $ make C_TEST=test_hello_world QUESTA=1
    $ make C_TEST=test_hello_world IES=1

Note that the appropriate simulators must be installed.

Dump Waves

For information about how to dump waves with XSIM, please refer to the section debugging-custom-logic-using-the-aws-hdk

System Verliog Tests

The system verilog tests can be found at verif/tests. Below is the information about each test.

test_gl_cntr.sv

Global counter test. Test programs and checks different global counter values.

test_hello_world.sv

A basic test that exercises the Hello World Register as well as the Virtual LED Register. It also includes a test that programs global counter in shell model. The test writes a value to the Hello World Register and then reads it back. Additionally, it reads the Virtual LED register.

test_null.sv

test_null is not a test. This is a system verilog module needed for HW/SW co-simulation.

HW/SW co-simulation Test

The software test with HW/SW co-simulation support test_hello_world.c can be found at software/runtime. For Information about how HW/SW co-simulation support can be added to a software test please refer to "Code changes to enable HW/SW co-simulation" section in RTL_Simulating_CL_Designs.

Using IPI to run simulations in cl_hello_world example

Xilinx IPI can also be used to simulate cl_hello_world. For information about how to use IPI to simulate cl_hello_world example, please refer to IPI_GUI_cl_hello_world_example
