Timing method and apparatus for digital logic circuits

A timing apparatus, comprising:

• a comparing unit for outputting a control signal according to a time value;
• a differentiated timing unit for outputting a timing signal with a timing granularity, wherein the timing granularity corresponds to the control signal;
• and
• a calculating unit for descending/ascending the time value according to the timing signal.

A timing apparatus, comprising:

• a comparing unit for outputting a control signal according to a time value;
• a differentiated timing unit for outputting an timing signal with a timing granularity, wherein the timing granularity is corresponded to the control signal;
• and
• an adder for outputting an adjusted time value to replace the time value according to the timing signal.

A timing method comprising:

• comparing a time value with at least one predetermined time interval value and generating a comparison result;
• generating a control signal according to the comparison result;
• outputting a timing signal according to the control signal;
• and
• descending/ascending the time value according to the timing signal;
• wherein the timing signal corresponds to one of a plurality of different granularities.
