While trying to convert a design in HyperLynx .HYP v2.14 to the .PCB format and noticed an error. QUCSSTUDIO reported it converted okay, but when trying to open the .PCB I received a message bad parameter. When I reviewed the file with Notepad I noticed no issues. When I opened the converted file with a binary file viewer I saw it attached the standard CR LF control characters (dec 13 and 10). Well it turns out for QUCSSTUDIO to read the .PCB format it can’t have the CR (dec 13) character only LF. I wrote a simple program to strip all CR characters from the converted .PCB file and it opens fine. So, either the .HYP -> .PCB converter needs to not add char 13, or, QUCSSTUDIO should read .PCB files supporting both CR and LF vs just LF.
