ABSTRACT:
Wiring topology and hierarchy of transmission line impedances for connecting I/O of semiconductor devices together. This arrangement gives smooth signal shapes for signal rise and fall times as fast as one (1) nsec or faster. The design uses a balanced multi-way branched net with increasing impedance until very close to the end, of the net, where it is a balanced multi-way branched net with unterminated ends. Thus, coming out of the signal driver is a single impedance transmission line. This single impedance transmission line (A) then branches into two impedance transmission lines (B), each having an impedance higher than the single line impedance that feeds it. These lines (B) are used to drive electronic modules. After entering the electronic modules through a connector, each of these lines (B) then branch into two transmission lines (C) having a yet higher impedance value. Each of these lines (C) finally ends in a cluster of four transmission lines (D. Each of these final lines (D) connects to electronic devices on the electronic module.
