Timing esimation method and simulator

A simulator, comprising:

• a processor;
• and
• a memory, electrically connected to the processor and configured to store at least one instruction;
• wherein when the processor executes the at least one instruction, the processor performs a timing estimation method applied to a function verification model for issuing access requests to simulate a situation in which the memory is accessed via a bus, and in the timing estimation method, wherein each slice corresponds to at least one of the access requests, and the processor performs:
• obtaining a first time point, at which the function verification model issues a first access request;
• obtaining a second time point, at which the function verification model receives a first response to the first access request from the bus;
• calculating a delay time between the first time point and the second time point;
• determining whether the delay time is longer than or substantially equal to a transmission time corresponding to the first access request;
• by the function verification model, issuing a second access request when the delay time is longer than or substantially equal to the transmission time corresponding to the first access request;
• by the function verification model, issuing the second access request in a compensation time counting from the second time point when the delay time is shorter than the transmission time corresponding to the first access request, wherein the compensation time is no longer than a difference between the transmission time and the delay time;
• obtaining a total transmission time for the access requests according to at least one slice type, a resolution of at least one frame or encoding scheme of the at least one frame that corresponds to the access requests;
• obtaining a total amount of access requests corresponding to the at least one frame;
• obtaining an average transmission time for the access requests according to the total transmission time and the total amount of access requests;
• and
• calculating a power consumption value according to the at least one slice type, the resolution of at least one frame or the encoding scheme of the at least one frame and the delay times.
