Systems, compute-implemented methods, and computer program products to facilitate automated waveform validation are provided. According to an embodiment, a system can comprise a processor that executes computer executable components stored in memory. The computer executable components comprise a waveform comparison component that compares a digital conversion of an analog signal to a reference signal.

Automated waveform validation

Techniques facilitating write-only device state inferences. In one example, a system can comprise a processor that executes computer executable components stored in memory. The computer executable components comprise: a monitor component; and a state component. The monitor component can compare a property of a feedback signal output by a write-only device with a reference signal. The state component can determine a state of the write-only device based on a comparison between the property and the reference signal.

Inferring the state of a write-only device by mapping control register values and feedback signal values

A memory system and method for storing data in one or more storage chips includes: one or more memory cards each having a plurality of storage chips, and each chip having a plurality of dies having a plurality of memory cells; a memory controller comprising a translation module, the translation module further comprising: a logical to virtual translation table (LVT) having a plurality of entries, each entry in the LVT configured to map a logical address to a virtual block address (VBA), where the VBA corresponds to a group of the memory cells on the one or more memory cards, wherein each entry in the LVT further includes a write wear level count to track the number of writing operations to the VBA, and a read wear level count to track the number of read operations for the VBA mapped to that LVT entry.

Hardware assisted high speed serial (HSS) transceiver testing including receiving, by a link layer hardware state machine on a HSS transmitting device, an instruction to generate a test pattern, wherein the test pattern comprises a sequence of data units; loading, by the link layer hardware state machine, each unique data unit into embedded random access memory (RAM); generating, by the link layer hardware state machine, the test pattern comprising the sequence of data units using the unique data units stored in the embedded RAM, wherein at least one of the unique data units is repeated in the sequence of data units of the test pattern; and sending, by the link layer hardware state machine, the generated test pattern to an input of a HSS transceiver.

Hardware error detection on a high-speed serial (HSS) connection including tracking, by a hardware state machine on a HSS receiver, errors in a data stream, wherein tracking, by the hardware state machine, the errors in the data stream comprises, for each sample of incoming data: inspecting, by the hardware state machine, a detected error indicator in a test control register to determine whether an error has been detected in the sample; incrementing, by the hardware state machine, an error count in a hardware error counter if the test control register indicates an error has been detected in the sample; clearing, by the hardware state machine, the detected error indicator if the test control register indicates an error has been detected in the sample; and incrementing, by the hardware state machine, a sample count in a sample count register.
