Method for automatically generating the simulation circuit netlist from a die to a voltage regulator module for power delivery simulations

Disclosed is a method for automatically generating the simulation circuit netlist from a die to a voltage regulator module for power delivery simulations. Benefits include improved reliability, decreased processing time, improved capacity for handling complex circuit designs. 

General description

              The disclosed method is a Visual Basic program that generates a circuit netlist suitable for simulation from a spreadsheet diagram. The program functions as a tool that converts a spreadsheet worksheet with a standardized syntax to a simulator-compatible netlist (see Figure 1).

              The key elements of the disclosed method include:

·        Visual Basic program code

·        Spreadsheet worksheet

·        Simulation circuit file

              The disclosed method addresses the following issues:

·        The length of time required to create a circuit simulator netlist using the conventional method

·        The ease with which errors occur within the conventional method

              These issues combine to limit the complexity of designs that can be analyzed for electrical performance when the conventional method is followed. The disclosed method enables the reliable analysis of more complex designs.

              The values that are typically documented when a netlist is created include, but are not limited to the resistance, inductance, capacitance, and currents associated with a particular circuit, including a motherboard, a package, capacitors and a die.

              The conventional method includes the manual creation of a netlist (typing by hand). The values are typically stored in a spreadsheet. However, the netlist and the spreadsheet are not necessarily synchronized.

Advantages

              The disclosed method provides several advantages. The time required to create the netlist is greatly reduced compared with the conventional method. The probability of errors introduced by the creation of the netlist is effectively minimized. Highly complex circuit designs can be effectively analyzed. 

Detailed description

              An acceptable simulator-compatible netlist statement consists of an element name, two node names, and a value for the element. The node names from the circuit and the values for the elements are stored in the spreadsheet (see Figures 2 and 3). For example, Figure 2 illustrates a spreadsheet with resistance information. Figure 3 illustrates a spreadsheet with inductance information. The node numbers are colored and bold (though the prog...
