Abstract: Some examples described herein relate to a design system and a method for printed circuit board (PCB) design. In an example, a design system includes a processor and a memory coupled to the processor. The memory stores instruction code. The processor is configured to execute the instruction code to provide a workspace in a user interface in which a PCB design comprising multiple layers is capable of being created; provide a list of layout templates in the user interface; and provide an insert function, via the user interface, configured to insert a selected layout template of the list of layout templates into the workspace to be included in the PCB design. Each layout template of the list of layout templates is a tile layout that includes a layout component and metal lines that extend to one or more edges of the tile layout.

Abstract: A method, computer system, and computer-readable medium for determining a first decoupling constant for circuitry. The method includes determining a target impedance value and a first step current value for the circuitry. The method also includes iteratively simulating a model of the circuitry while adjusting a first number of first decoupling capacitors until impedance across a range of frequencies is below the target impedance value to obtain a first final number of first decoupling capacitors. The method further includes calculating a first decoupling constant based on the first step current value and the first final number of first decoupling capacitors.
