Filed: 1990-03-13
Abstract: PURPOSE:To eliminate the need for a pulse generator by connecting a circuit for positive feedback between an input and an output terminal, turning on the circuit for positive feedback in test mode and evaluating whether logic is true or false from whether oscillation occurs or not, and evaluating a delay time with the oscillation frequency. CONSTITUTION:One input terminal 12 and the output terminal 14 of the logic gate circuit 10 are connected to each other by the circuit 18 for positive feedback which consists of inverters 15 and 16 and a transmission gate 17, which controls the connection and disconnection of the circuit 18 with and from the circuit 10. For the evaluation, and the input terminals 11 and 13 are grounded and applied with a level 'L', a source voltage is applied to a control voltage to applies a level 'H'. In this test mode, the circuit 18 is connected between the input and output of the circuit 10 to constitute a ring oscillator. The inverter 15 makes the number of stages of the ring 15 odd, so this inverter is not necessary when there are an odd number of stages present between the input and output of the circuit 10. Consequently, when the logic of the circuit 10 is true, oscillation is started, so its frequency is detected to find the delay time between the input and output from a specific expression.

Inventor: MATSUDAIRA NAOKI
IPC: G06F5/00
Filed: 1990-03-13
Abstract: PURPOSE:To attain high speed operation by extracting an output of n-set of flip-flops of a shift register as a parallel data in a timing given by a frequency division output from a frequency divider circuit. CONSTITUTION:An initial value of a 1st logic level is set to m-set of consecutive flip-flops less than the number (n) at the reset of each flip-flop and an initial value of a 2nd logic level different from the 1st logic level is set to remaining (n-m) sets of consecutive flip-flops. Then a frequency divider circuit 10 generates a frequency division waveform (output clock) whose frequency is 1/n to an input clock frequency given to each flip-flop 1-i (i=1,2,...,n) and whose duty factor is m/nX100%. That is, a serial input data with an input frequency is shifted-in sequentially to a flip-flop 6-i of a shift register 60 and outputs of the n-set of flip-flops 6-i of the shift register 60 are extracted as parallel data in a timing given by a frequency division output from the frequency divider circuit 10. Thus, high speed operation is attained.
