// DESCRIPTION: Verilator: Verilog Test module
|
|
//
|
|
// A test of the +1364-1995ext+ and +systemverilogext+ flags.
|
|
//
|
|
// This source code contains constructs that are valid in SystemVerilog 2009
|
|
// but not in Verilog 1995. So it should fail if we set the language to be
|
|
// Verilog 1995, but not SystemVerilog 2009.
|
|
//
|
|
// Compile only test, so no need for "All Finished" output.
