From "Practical UVM"

The code from “Practical Guid to Adopting the Universal Verification Methodology(UVM)” by
Rosenberg and Meade:
// Compile the UVM package
`include “uvm_pkg.sv”

module hello_world_example();
// Import the UVM library and include the UVM macros
import uvm_pkg::*;
include "uvm_macros.svh" initial begin uvm_info(“info1”,“Hello World!”, UVM_LOW)
end
endmodule: hello_world_example
Compiled in Questasim via:

doHello

set MTI_HOME c:/questasim64_10.0c
set UVM_HOME $MTI_HOME/verilog_src/uvm-1.1
setenv MTI_HOME c:/questasim64_10.0c
setenv UVM_HOME $MTI_HOME/verilog_src/uvm-1.1
vlog -64 c:/questasim64_10.0c/verilog_src/uvm-1.1/src/uvm_pkg.sv
vlog -64 hello.sv
When I attemp to simulate this example:
vsim hello_world_example

vsim hello_world_example

** Fatal: (vsim-7019) Can’t locate a C compiler for compilation of DPI export tasks/functions.

I have visual C++ Express. Why isn’t Mentor using that?

The book you’re reading is out of date wrt to the current version of the UVM - that’s the problem with books. It was written for UVM 1.0EA which was basically OVM with the O’s changed to U’s, UVM has moved on since then.

One of the things that changed is that the UVM uses a DPI package now, that is why you are getting the error.

If you compile using the following lines with Questa 10.0c, the example will work:

vlog -64 hello.sv
vsim hello_world_example

This is because if you compile your own UVM package, Questa will assume that you have compiled your own version of the DPI to go with the UVM package you are using.

Please see Verification Methodology Cookbooks | Coverage, UVM and OVM | Verification Academy for more up to date information on how to use and apply the UVM.
