DVT SystemVerilog IDE User Guide
Rev. 21.1.2, 18 January 2021
To generate the Component Diagrams from simulation, some additional arguments must be added to the build directives, depending on the simulator.
When the simulation starts, a component_hierarchy_of_<test_name>.chd will be generated in the working directory. Open the generated file in DVT to inspect the diagram.
The location of the diagram can be changed by setting the DVT_CHS_FILE environment variable before running the simulation.
export DVT_CHS_FILE=/path/to/a/components_diagram.chd # sh, bash
You can stop the test immediately after the diagram has been generated by setting the DVT_CHS_STOP_TEST environment variable before running the simulation.
export DVT_CHS_STOP_TEST=true # sh, bash
