Abstract

The invention provides a noise processing method and a circuit after a noise processing process. The circuit after the noise processing process comprises at least two disturbed lines and at least one disturbing line. The number of parallel lines among the at least three line does not exceed two. Parallel portions exist between the disturbed lines and the disturbing line. Common parallel portions exist between the disturbed lines. The width of a gap between the common parallel portions is wider than or equal with a sum value of two times the width of a minimum line gap and the width of the line.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a noise processing method and a circuit after noise processing. Background technique [0002] At present, for circuits with noise violations, the traditional solution is to remove the parallel interfering traces on the traces that cannot meet the voltage threshold requirements on the disturbed traces, so as to meet the voltage threshold requirements. [0003] in particular, figure 1 A schematic of the multipath noise offending circuit is shown. figure 2 Shown is a schematic diagram of the circuit after noise processing using the conventional scheme. Please also refer to figure 1 and figure 2 . Wherein, each line in the figure represents one routing, and the crossed ones represent two routings. [0004] Such as figure 1 As shown, the multipath noise offending circuit includes two victim traces (i.e., trace e and trace f) and five offending traces (i.e., trace a, trace b, trace ...
