Sub ID a

Signal names shall be defined for signal lines that output from important blocks. The signal name shall be provided once, at the origin of the signal line.

A label shall be used to display defined signal names.


An important block is defined by the system input and output of meaningful results, not by its type.

Custom Parameter
