Abstract
A method of preserving signal integrity of buses is disclosed. One step of the method includes the step of forming between a first bus and a first bus port of a bus controller, a first stub that is no greater than a first maximum stub length allowed for the first bus by terminating the first bus with a first terminating circuit if (i) the first bus port does not have at least one device coupled thereto, and (ii) a second bus port of the bus controller does have at least one device coupled thereto. The method also includes the step of forming between the first bus and a second bus port of the bus controller, a second stub that is no greater than the first maximum stub length allowed by terminating the first bus with a second terminating circuit if (i) the first bus port does have at least one device coupled thereto, and (ii) the second bus port does not have at least one device coupled thereto. Apparatus for implementing the method are also disclosed.
