Timing simulation system and method

Abstract

The invention discloses a timing simulation system and method. The timing simulation system is applied to the simulation of an internal integration circuit and comprises a processing unit, a first communication unit, a second communication unit, a signal transmission unit and a power supply. According to the invention, a high-impedance load is arranged on an I2C bus and then is connected to the power supply and the timing of an I2C is simulated by using software, thus the problem of I2C electric leakage can be improved, and the consumption of power is reduced.

Description

technical field [0001] The present invention relates to a timing simulation system and method thereof, especially to simulate an internal circuit for information exchange between a processing unit and peripheral equipment, so as to further increase the ports for information exchange between the processing unit and peripheral equipment and reduce power consumption. Background technique [0002] I 2 There are many C interfaces, but the dedicated I 2 The C interface is very limited, so two push-pull IO ports are commonly used to simulate I 2 C interface, and then through software simulation I 2 C timing, but there are certain problems in the traditional software simulation method, mainly because the considerable leakage current generated by the leakage will cause the jitter of the power supply, and the traditional I 2 C power consumption is higher. [0003] For the push-pull IO port, its structure is as follows figure 1 , The IO port is determined by the direction bit TRIS...
