Title: Test method for a digital to analogue converter
Inventor: O'DWYER THOMAS GERARD
IPC: H03M1/10
Filed: 1991-11-21
Abstract: The method determines the maximum positive and maximum negative deviations from ideal of the analogue output signal of a digital to analogue converter with twelve digital input pins. A set of sixteen tests is carried out to determine the maximum positive deviation, while a set of sixteen tests is carried out to determine the maximum negative deviation. During the set of tests to determine the maximum positive deviation, the binary values of the signals on the eight least significant input pins, namely pins 5 to 12, are maintained at constant values. Every combination of binary values are applied to the most significant pins 1 to 4. The values of the binary signals applied to the least significant pins 5 to 12 are selected using an orthogonal array to give the most positive deviation. Similar tests are carried out to determine the maximum negative deviation, with the exception that the binary signals applied to the least significant pins 5 to 12 are selected to give the most negative deviation.

Title: Dynamic logic with completion detection
Inventor: MARTIN ROBERT J
IPC: G06F7/00
Filed: 1993-05-18
Abstract: A clocking system 600 and method 800 are provided for logic blocks 602 having cascaded self-timed dynamic logic gates. The dynamic logic gates are precharged in parallel and perform self-timed logic evaluation on vector inputs 610 to derive a vector output 612. An evaluation done detector 604 monitors the vector output 612 of the logic block 602 and determines when the vector output 612 is valid. An edge detector 608 detects the rising and falling edges of an arbitrary periodic timing signal 620. Finally, a logic block clock generator 606 is set by the edge detector 608 and reset by the evaluation done detector 60450 as to provide precharging signals 618 to the logic block 602, thereby defining respective precharge and evaluation periods for the logic block 602. In a specific implementation, the speed of logic evaluations is twice the speed of the system clock. <IMAGE>
