Abstract(in English) | The problem of increasing the size of QFP majority logic circuits is considered.Previously,in order to achieve a yield of 30% the largest circuit size is limited to 300 QFP′s.If the signal level is increased by reducing the number of input, output lines without worsening parameter fluctuations,an exponential increase in circuit size for the same yield is expected.If the signal current level is 1/5 of the total QFP output current(previously 1/ 8),a 10000-QFP circuit has an expected yield of 90%.The trade-offs are a small increase in delay and more severe wiring constraints. It is shown that a 32-bit fixpoint adder with 32 ps pipeline pitch can achieve a fall-through delay of 176 ps using 3200 QFP′s. |
