Model-building method for building top interface logic model

A model-building method, comprising

• reading a top netlist and a block model, wherein the top netlist comprises a first input node, a first output node and at least one multivibrator, the block model comprises at least one input node and at least one output node;
• obtaining a first subnetlist from the top netlist, wherein the first subnetlist comprises at least one component coupled between the at least one input node of the block model and the first input node or between the at least one input node of the block mode and the at least one multivibrator;
• obtaining a second subnetlist from the top netlist, wherein the second subnetlist comprises at least one component coupled between the at least one output node of the block model and the first output node or between the at least one output node of the block model and the at least one multivibrator;
• obtaining a third subnetlist from the top netlist, wherein the third subnetlist comprises at least one component coupled between a clock input node of the at least one multivibrator and a top clock input node of the top netlist;
• and
• generating a top ILM according to the first subnetlist, the second subnetlist, and the third subnetlist.
