Electronic design automation is used extensively to ensure that designers do not violate design rules; a process called design rule checking (DRC). DRC is a major step during physical verification signoff on the design, which also involves LVS ( layout versus schematic ) checks, XOR checks, ERC ( electrical rule check ), and antenna checks.
A cut-down version of RDOS, without real-time background and foreground capability but still capable of running multiple threads and multi-user Data General Business Basic, is called Data General Diskette Operating System [4] (DG-DOS or now—somewhat confusingly—simply DOS); another related operating system is RTOS, a Real-Time Operating ...
The emphasis is on compactness and speed of execution. FreeRTOS can be thought of as a thread library rather than an operating system, although command line interface and POSIX-like input/output (I/O) abstraction are available. FreeRTOS implements multiple threads by having the host program call a thread tick method at regular short intervals.

An RTOS that can usually or generally meet a deadline is a soft real-time OS, but if it can meet a deadline deterministically it is a hard real-time OS. [3] An RTOS has an advanced algorithm for scheduling. Scheduler flexibility enables a wider, computer-system orchestration of process priorities, but a real-time OS is more frequently dedicated ...
In embedded systems, a board support package (BSP) is the layer of software containing hardware-specific boot firmware, runtime firmware and device drivers and other routines that allow a given embedded operating system, for example a real-time operating system (RTOS), to function in a given hardware environment (a motherboard), integrated with the embedded operating system.
In computer science, rate-monotonic scheduling (RMS) [1] is a priority assignment algorithm used in real-time operating systems (RTOS) with a static-priority scheduling class. [2] The static priorities are assigned according to the cycle duration of the job, so a shorter cycle duration results in a higher job priority.
LVS checking involves following three steps: Extraction: The software program takes a database file containing all the layers drawn to represent the circuit during layout. It then runs the database through many area based logic operations to determine the semiconductor components represented in the drawing by their layers of construction.
