Embodiments of the present disclosure are directed towards techniques and configurations for ground via clustering for crosstalk mitigation in integrated circuit (IC) assemblies. In some embodiments, an IC package assembly may include a first package substrate configured to route input/output (I/O) signals and ground between a die and a second package substrate. The first package substrate may include a plurality of contacts disposed on one side of the first package substrate and at least two ground vias of a same layer of vias, and the at least two ground vias may form a cluster of ground vias electrically coupled with an individual contact. Other embodiments may be described and/or claimed.

Ground via clustering for crosstalk mitigation

Embodiments described herein may be directed to receiving a plurality of data captured, respectively, by a plurality of test instruments coupled to a device under test, wherein a plurality of data elements within, respectively, the plurality of captured data are associated with a timestamp based upon a time a data element was captured. Embodiments may also analyze the received plurality of data captured, respectively, by the one or more test instruments, and graphically display at least a portion of the analyzed plurality of captured data to a user. Other embodiments may be identified herein.

Debug tool for test instruments coupled to a device under test

A device and method of utilizing an interconnect bridge to electrically couple two semiconductor dies located on different surfaces. Integrated circuit packages using an interconnect bridge to electrically couple a semiconductor die on a substrate to a semiconductor die on a motherboard are shown. Integrated circuit packages using an interconnect bridge to electrically couple a semiconductor die on a top surface of a substrate to a semiconductor die on a bottom surface of a substrate are shown. Methods of electrically coupling semiconductor dies on different surfaces using interconnect bridges are shown.

Side mounted interconnect bridges

Integrated circuit (IC) chip 'on-die' interconnection features (and methods for their manufacture) may improve signal connections and transmission through a data signal communication channel from one chip, through semiconductor device packaging, and to another component, such as another chip. Such chip interconnection features may include (1) 'last silicon metal level (LSML)' data signal &#x201c;leadway (LDW) routing&#x201d; traces isolated between LSLM isolation (e.g., power and/or ground) traces to: (2) add a length of the isolated data signal LDW traces to increase a total length of and tune data signal communication channels extending through a package between two communicating chips and (3) create switched buffer (SB) pairs of data signal channels that use the isolated data signal LDW traces to switch the locations of the pairs data signal circuitry and surface contacts for packaging connection bumps.

Rlink-on-die interconnect features to enable signaling

Integrated circuit (IC) chip die to die channel interconnect configurations (systems and methods for their manufacture) may improve signaling to and through a single ended bus data signal communication channel by including on-die induction structures; on-die interconnect features; on-package first level die bump designs and ground webbing structures; on-package high speed horizontal data signal transmission lines; on-package vertical data signal transmission interconnects; and/or on-package electro-optical (EO) connectors in various die to die interconnect configurations for improved signal connections and transmission through a data signal channel extending through one or more semiconductor device package devices, that may include an electro-optical (EO) connector upon which at least one package device may be mounted, and/or be semiconductor device packages in a package-on-package configuration.

Rlink&#x2014;die to die channel interconnect configurations to improve signaling

Integrated circuit (IC) chip 'on-die' inductor structures (systems and methods for their manufacture) may improve signaling from a data signal circuit to a surface contact of the chip. Such inductor structures may include a first data signal inductor having (1) a second end electrically coupled to an electrostatic discharge (ESD) circuit and a capacitance value of that circuit, and (2) a first end electrically coupled to a the data signal surface contact and to a capacitance value at that contact; and a second data signal inductor having (1) a second end electrically coupled to the data signal circuit and a capacitance value of that circuit, (2) a first end electrically coupled to the second end of the first data signal inductor, and to the capacitance value of the ESD circuit. Inductor values of the first and second inductors may be selected to cancel out the capacitance values to improve signaling.
