Embodiment 1
[0030] Such as figure 1 Shown is a method for realizing the remote reading of CPLD version, and described method comprises the following steps:
[0031] 1. Write the version number of the CPLD into the UFM through the initialization file. The specific implementation process is:
[0032] 1) Set the initialization file so that its data represents the current CPLD version information. UFM is a flash module inside CPLD that is specially used by users. Users can assign values to internal data through logical operations or initialization files. Because this article only involves reading the version number, the data will not change. Therefore, the version number information of the CPLD can be generated by means of an initialization file.
[0033] 2) Instantiate the UFM and I2C modules. The UFM module belongs to the hard core design inside the CPLD. In actual use, the instantiation operation should be performed first, and the I2C module should be selected during the instantiatio...
Embodiment 2
[0042] Such as figure 2 Shown is a method for realizing the remote reading of CPLD version, and described method comprises the following steps:
[0043] 1. Write the version number of the CPLD into the UFM through the initialization file. The specific implementation process is:
[0044] 1) Set the initialization file so that its data represents the current CPLD version information. UFM is a flash module inside CPLD that is specially used by users. Users can assign values to internal data through logical operations or initialization files. Because this article only involves reading the version number, the data will not change. Therefore, the version number information of the CPLD can be generated by means of an initialization file.

Embodiment 3
[0055] On the basis of Embodiment 1, the operation instructions are added as follows when reading and writing UFM:
[0056] Close the I2C channel of the corresponding port through the 0x26 and 0xFF commands.
[0057]Adding this step can close the reading channel after reading the version information, so as to avoid occupying the I2C channel all the time and affecting the use.
