Problems solved by technology

In the prior art, the truth table of the logic circuit is obtained by writing the stimulus file through the simulation tool, but this method cannot automatically analyze the input and output ports, and the general simulation tool runs for a long time and the extraction method is complicated, so the truth table of the logic circuit cannot be analyzed. Fast extraction, the higher the complexity of the logic circuit, the more significant this technical problem

Abstract

The embodiment of the invention discloses a logic circuit truth table determination method and device and electronic equipment, relates to the technical field of electronic circuits, and can quickly extract a truth table of a logic circuit. The method comprises the following steps: assigning an input port of a logic circuit described by a netlist based on a first group of input truth values in an input truth value list; the input true value list is pre-generated according to the input port of the logic circuit described by the netlist; calculating a level value of the output port of the logic circuit described by the netlist based on the assignment of the input port; judging whether a level value of the output port is calculated or not; and if the level value of the output port is calculated, taking the calculated level value of the output port as an output truth value corresponding to the first group of input truth values. The method is suitable for truth table extraction of the logic circuit.

Description

technical field [0001] The present invention relates to the technical field of electronic circuits, and in particular, to a method, a device and an electronic device for determining a truth table of a logic circuit. Background technique [0002] Electronic circuits are divided into two categories, one is circuits that transmit and process analog signals, called analog circuits; the other is circuits that transmit and process digital signals, called logic circuits. [0003] In the electronic design process, it is often necessary to extract the truth table of the logic circuit. In the prior art, a simulation tool is used to write an excitation file to obtain the truth table of the logic circuit, but this method cannot automatically analyze the input and output ports, and the general simulation tool has a long running time and a complicated extraction method, so the truth table of the logic circuit cannot be analyzed. Fast extraction, the higher the complexity of the logic cir...
