Systems and methods are disclosed for audio group identification for conferencing. For example, methods may include joining a conference call using a network interface; accessing an audio signal that has been captured using a microphone; detecting a control signal in the audio signal; and, responsive to detection of the control signal, invoking modification of an audio path of the conference call.

Audio group identification for conferencing

Using verification IP (VIP), the related design IP (DIP) can be integrated into a system on a chip (SOC) without requiring the IP component. Using a normalized framework, a software module can be integrated into the VIP software stack enabling the customized management of the VIP beyond the standard specification defined behaviors. Then, the modified software stack can be used to manage both behaviors defined by the specification and the design specific behaviors. The VIP can then be used in place of the DIP for SOC development.

VIP assisted method and apparatus to enable SOC integration and software development

In a system and method that simulates a design including a third party IP component, a driver for the IP component is compiled and executed in a workstation implementing the simulation platform for the design. The source code for the driver is modified to allow the simulation to reroute certain functions that would cause the simulator to hang until an event occurs that would unlock the simulation. The rerouting includes storing instruction location, state information, and any other context information needed to restore a paused function. The saved information is stored in a stack that is traversed upon detection of the event.

Enabling IP execution on a simulation execution platform

A system and method that tests an IP component of a hardware design generates an abstract model of the IP component based on knowledge of the design and one or more protocols implemented with the IP component. A generic driver and associated interfaces are additionally generated or selected to test the IP component within the hardware design.
