Title: Method for verifying combination loop system
Inventor: YAN SHAA
IPC: G06F17/50
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a design verifying method for verifying the design of hardware through the use of combination loop logic. SOLUTION: A model chekker provides the design verifying system by which the chekker receives both of the set of the mathematical expression of functionality in design and characteristics to be collated in the inspection of a mathematical model. The model is changed when an output directly relies on the output of a combination loop itself and a design includes the combination loop which requires an logical end within a single bus cycle. The least number of flip-flop is added to the combination loop first in order to break combination subordinate properties. Then the whole design state and the whole machine model state are compensated by a twin state being exactly the same as an original state. When the present state is the original state, the machine state proceeds to the twin state of the specified original state in a succeeding cycle.  When the present state is the twin state, the state machine proceeds to the succeeding new original state. Thus, the model is changed by a general and direct method so that the design including the combination loop is verified by the verifying system being available at present without changing the model checker itself.

Filed: 2000-04-05
Abstract: PROBLEM TO BE SOLVED: To increase the efficiency of the seedling plantation by allowing the conveying interval between mutually adjacent two seedlings to exactly coincide with the interval of the planted seedlings. SOLUTION: Among seedlings Pn and Pn+1 that are adjacently conveyed on the conveying speed-changeable conveyer 99, the conveying distance of the preceding seedling Pn from the time when the preceding seedling is detected by the sensor S2 to the time when the following seedling Pn+1 is detected by the sensor S2 is measured to calculate the conveying interval t and the calculated conveying interval is compared with the seedling-planting interval.
