System and method for design of high speed signaling and power delivery

#This disclosure relates generally to Information Handling Systems (IHSs), and more specifically, to printed circuit boards (PCBs) used in IHSs.

#As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an Information Handling System (IHS). An IHS generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, IHSs may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in IHSs allow for IHSs to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, global communications, etc. In addition, IHSs may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

#An IHS may include one or more printed circuit boards (PCBs). A variety of electrical hardware components may be mechanically coupled to a PCB. The electrical hardware components may also be electrically coupled to various circuit pathways provided by the PCB. PCBs may be utilized within a wide variety of devices and machines. For example, in the context of personal and enterprise computing, PCBs may be used to construct motherboards, microcontrollers, memories, storage devices, peripherals cards (e.g., network interface cards) and a wide variety of other electronic components.

#The present invention(s) is/are illustrated by way of example and is/are not limited by the accompanying figures, in which like references indicate similar elements. Elements in the figures are illustrated for simplicity and clarity, and have not necessarily been drawn to scale.

#FIG. 1 is a block diagram depicting certain components of an IHS according to various embodiments.

#FIG. 2 is a diagram of a cross-section of a PCB illustrating certain aspects of a via portion of a PCB signal pathway.

#For purposes of this disclosure, an IHS may include any instrumentality or aggregate of instrumentalities operable to compute, calculate, determine, classify, process, transmit, receive, retrieve, originate, switch, store, display, communicate, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an IHS may be a personal computer (e.g., desktop or laptop), tablet computer, mobile device (e.g., Personal Digital Assistant (PDA) or smart phone), server (e.g., blade server or rack server), a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. An IHS may include Random Access Memory (RAM), one or more processing resources, such as a Central Processing Unit (CPU) or hardware or software control logic, Read-Only Memory (ROM), and/or other types of nonvolatile memory.

#Additional components of an IHS may include one or more disk drives, one or more network ports for communicating with external devices as well as various I/O devices, such as a keyboard, a mouse, touchscreen, and/or a video display. An IHS may also include one or more buses operable to transmit communications between the various hardware components. An example of an IHS is described in more detail below. FIG. 1 shows an example of an IHS configured to implement the systems and methods described herein according to certain embodiments. It should be appreciated that although certain IHS embodiments described herein may be discussed in the context of an enterprise server computer comprised within an enterprise system of similar enterprise servers, other embodiments may be utilized.

#FIG. 1 is a block diagram of an IHS 100 that may utilize various components that may utilize a PCB milled according to the embodiments described herein. In various embodiments, IHS 100 may execute program instructions that cause IHS 100 to perform certain of the operations disclosed herein. While a single IHS 100 is illustrated in FIG. 1, IHS 100 may be a component of an enterprise system that may include any number of additional IHSs that may also be configured in the same or similar manner to IHS 100. An IHS 100 may also be a personal computing device, such as a laptop, tablet or smartphone device. An IHS may also be an appliance, an audio device, a video device, a gaming device, a virtual reality device, a networking device or any machine that includes a PCB.
