IME, The different connection styles apply only to the auto router. You can (I've used this before) select several nets (make a class for them) and have P99SE make them the same length using the "Tools-EqualizeNetLengths"
They don't look as nice as if you do it by hand and then just DRC the rule, but it does work. -----Original Message----- From: Adeel Malik [mailto:[EMAIL PROTECTED]] Sent: Tuesday, August 13, 2002 7:10 AM To: Protel EDA Forum Subject: Re: [PEDA] Matched Lenghth Constraint Hi Bob, I am not talking of routing these tracks through Auto-Router. I wanna say that how the Design Rule Checker of Protel checks the matched lengths and what is the effect of having various connection styles , e.g. 90 degree conection and 45 degree connection.

I tried it a few times where there was plenty of room to match the lengths of a delay loop and they were not even close so eneded up having to manually route these. I would also love to hear if there was a way in 99SE to get the system to match these lengths.
