ASIC implementing real-time spectrum analysis
16 Jan 24
A real-time spectrum analyzer (RTSA) includes an analog-to-digital converter (ADC) configured to convert in real-time an input analog signal into a digital input data stream, a digital down-converter (DDC) configured to down-convert in real-time the digital input data stream into a down-converted input data stream, a fast Fourier transform (FFT) unit configured to generate in real-time FFTs of the down-converted input data stream, an acquisition memory circuit configured to store in real-time the FFTs generated by the FFT unit, and an analyzer configured to read in non-real time the FFTs stored in the acquisition memory.

Utility
Methods, Systems, and Computer Readable Media for Capturing Dropped Packets at a Switching Fabric Emulator
11 Jan 24
One example method occurs at a switching fabric emulator providing an emulated switching fabric comprising emulated switching elements and associated packet queues, wherein the switching fabric emulator comprises at least one switching application-specific integrated circuit (ASIC) or programmable switching chip, the method comprising: during a test session: receiving, via at least a first physical port of the switching fabric emulator, packets from or to a system under test (SUT); detecting an occurrence of a dropped packet that happens while the packet is traversing the emulated switching fabric; encapsulating dropped packet data associated with the dropped packet, wherein the encapsulated dropped packet data indicates an emulated switching element or packet queue contributing to the occurrence of the dropped packet; and providing the encapsulated dropped packet data to an analyzer.
