Judson - thanks for your question. I am going to move it to the product-specific HyperLynx community where it will receive greater visibility. The Member Resources community is for general community questions and suggestions.
Also, I noticed that your username - the one that is displayed to others, seems to be your email address. When you are logged in, your name is displayed to you, but others see your user name. Many people prefer to not have their email address displayed. If you would like me to change your username to something different, I would be happy to. Or, if it was intentional, I will leave it as is.
Thankyou, i have recieved the needful help.
The demo files are found in the HyperLynx SI installation folder in a folder named HypFiles. For example in the 64-bit version of HyperLynx VX.2.4 they are in C:\MentorGraphics\HLVX.2.4\SDD_HOME\hyperlynx64\HypFiles.
