MONITOR CIRCUIT, LOGIC ANALYSIS TERMINAL AND SYSTEM, AND DELAY MEASURING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To dispense with a measuring apparatus for external observation by facilitating the observation of an observation object signal without reducing the degree of freedom in arrangement and wiring.SOLUTION: The monitor circuit includes: a first multiplexer that receives observation object signals of an observation object node, and selects and outputs one observation object signal in response to a first selective signal; and a second multiplexer that receives a plurality of clock signals, and selects and outputs one clock signal in response to a second selective signal. At least one of the first and second multiplexers includes a multiplexer for suppressing the propagation of a glitch to the output when the polarity of at least one signal input of a plurality of signal inputs changes.SELECTED DRAWING: Figure 13
