The invention discloses a control method for display fields of an instrument. The control method is executed by an instrument device cooperating with multiple monitoring devices which can be on-line with the instrument device. The instrument device comprises a screen, a memory and a processor. The method comprises the following steps: (A) the memory pre-stores multiple pieces of field configuration data, and the processor displays measured values measured by a first group of monitoring devices on the screen according to one piece of field configuration data; (B) the processor detects an on-line state, judges whether the instrument device is on-line with the first group of monitoring devices or not, and if no, enters step (C); (C) the number of the on-line monitoring devices is calculated; (D) the processor reads a piece of field configuration data corresponding to the number of the on-line monitoring devices from the memory, and correspondingly displays the measured values measured by the on-line monitoring devices on the screen. According to the control method, a field configuration manner is automatically regulated by detecting the on-line state, and information is displayed in a more striking manner.

The invention discloses a method for achieving random verification through normal distribution, and relates to the field of chip random verification. Random verification controllability and accuracy are achieved by controlling parameters. A needed chip verification environment is built at first, and used as an input to be connected with a normal distribution part; internal processing is carried out after normal distribution is input, the internally-processed data are output to an output result module after being handled, and a random verification result formed after mathematical distribution is obtained. According to the method, random verification can achieve the expected result more efficiently, the chip random verification efficiency and accuracy are improved, and the whole verification process is clearer.
