[0022] Such as figure 2 Shown is the flow chart of the method of the present invention, the layout and principle of the multi-voltage chip design of the embodiment of the present invention Figure one The consistency comparison method includes the following steps:
[0023] Step 1. Use PERL to modify the script file MPower.pl of the layout netlist. The following steps are included when modifying the MPOwer.pl:
[0024] Step 1A. Find out the name of each power port of each functional module of the chip and the power domain to which each power port belongs. Each of the functional modules includes two categories: power normally-on modules and power-off modules.
[0025] Step 1B. According to the name of each power port of each of the functional modules, respectively add the module and the power port of the standard unit corresponding to each of the power port names in the layout netlist.
[0026] Step 1C: According to the power domain to which each functional module belongs, add each po...
