Transceiver toolkit commands

Thank you so much your help

But, we already found that PRBS7 is the most appropriate one.

I have one more question.

I want to use a tcl package (tcom) which is for arranging data (number of bits, error, and BER) in xlsx file

I downloaded tcom in

C:/altera/13.1/quartus/bin64/tcl8.5

C:/altera/13.1/quartus/bin64 C:/altera/13.1/quartus/lib

However, when I tried "package require tcom",

quartus indicated as

Error:ERROR: Can't load library: C:\altera\13.1\quartus\bin64\tcl8.5\tcom\tcom.dll. The operating system reports the following error: ÀÛ¾÷À» ¿Ï·áÇß½À´Ï´Ù.

or Error:can't find package tcom

How can I solve this problem?

Location that Tcl looks in when searching for libraries isn't right?

or Is there any problem in dll file?

Thanks.
