你写的是VHDL用的是verilogHDL的编译器。多么白痴的错误啊。将adder16b.v改成adder16b.vhd

VUnitis anopen sourceunit testing framework for VHDL/SystemVerilog. It features the functionality needed to realize continuous and automated testing of your HDL code. VUnit doesn't replace but rather complements traditional testing methodologies by supporting atest early and oftenapproach through automatio...
Syntax Verilog Modules Modules are the building blocks of verilog designs. They are a means of abstraction and encapsulation for your design A module consists of a port declaration and verilog code to implement the desired functionality Modules should be created in a verilog file where the filename...
