about Testbench architecture (VHDL)

[lahrach]

hi friends,

what is the meaning of configuration file in the tstbench architecture, can you give me a example.

thanks

Often configuration and data files are used in conjunction with testbenches to offer another layer of abstraction.

Suppose you want to test your design and implementation with various devices providing data input or accepting data output. By encapsulating these external devices in a configuration and/or data file, you keep the details of these devices outside of your design. This allows you to test your design with different test cases and isolates the influence of the external devices from your design.

Use of Generics : Any important device and system parameters which required to be changed at different abstraction levels were declared as generics, and the values for these were provided only in the configuration file. In this way, while simulating the UUT at different abstraction levels, the values of generics which had to be modified were done so only in the configuration file without having to change the test bench code.

Does this help answer your question?
