In summary, the conversation discusses the installation of xilinx and modelsim for a digital circuit design lesson. The speaker encountered a problem while running the testbench simulation and received error messages related to a formal port without an associated actual. The speaker later discovered their mistake and apologized for any confusion.

For the digital circuit design lesson we have to install xilinx and modelsim. After I designed the circuit and run the testbench simulation, I encountered a problem.

I understand the frustration of encountering errors and issues in the process of designing and testing digital circuits. It is important to troubleshoot and solve these problems in order to ensure accurate and reliable results.

In this case, it appears that there is an error in line 90 of the intro.vhf file, where a formal port "i" does not have an actual associated with it. This could be due to a mistake in the code or in the testbench setup. I would recommend carefully reviewing the code and checking for any missing or incorrect connections. Additionally, it may be helpful to consult the documentation for ModelSim XE III 6.2g for any specific guidelines or troubleshooting tips.

If the issue persists, it may be helpful to consult with a more experienced colleague or seek support from the software company. It is important to address and resolve these issues in order to ensure accurate and reliable results in digital circuit design.
