Hi culchie,

Thanks for your suggestions. The reason why my script did not work was similar to what you suggested. I did modify the Xor.hdl file located in the same directory where Xor.tst and Xor.cmp are located(under the downloaded project01 folder). But, I forgot to modify the Or.hdl that was being used in my Xor.hdl file. That is, the Or.hdl file was incomplete. Once I completed the implementation of all the chips used in the Xor.hdl file, it ran without error. The key is to make sure that all the chips being called are working correctly.

Thanks again. It always helps even if some one suggests something related to the bug if not exactly a solution.
