Timing Library Format (abbreviated TLF) is a file format used by electronic design automation tools. A TLF file is a text file in nature [1] and contains timing and logical information about a collection of cells (circuit elements). The TLF file contains information on the timing and power parameters of the cell library.
In revision 1.2, released in 2013, a new "Reduced Blanking Timing Version 2" mode was added which further reduces the horizontal blanking interval from 160 to 80 pixels, increases pixel clock precision from ±0.25 MHz to ±0.001 MHz, and adds the option for a 1000/1001 modifier for ATSC/NTSC video-optimized timing modes (e.g. 59.94 Hz instead ...
Standard Delay Format (SDF) is an IEEE standard for the representation and interpretation of timing data for use at any stage of an electronic design process. It finds wide applicability in design flows, and forms an efficient bridge between dynamic timing analysis and static timing analysis.
PDFtk (short for PDF Toolkit) is a toolkit for manipulating Portable Document Format (PDF) documents. [ 3 ] [ 4 ] It runs on Linux , Windows and macOS . [ 5 ] It comes in three versions: PDFtk Server ( open-source command-line tool ), PDFtk Free ( freeware ) and PDFtk Pro ( proprietary paid ). [ 2 ]
The full-timecode specification is of the form "IRIG J-xy", where x denotes the variant, and y denotes a baud rate of 75×2 y. Normally used combinations are J-12 through J-14 (300, 600, and 1200 baud), and J-25 through J-29 (2400 through 38400 baud).
The most recent full version is CTA-861-I, [19] published in February 2023, available for free after registration. It combines the previous version, CTA-861-H, [ 20 ] from January 2021 with an amendment, CTA-861.6, [ 21 ] published in February 2022 and includes a new formula to calculate Video Timing Formats, OVT.

The Timing closure in VLSI design and electronics engineering is the process by which a logic design of a clocked synchronous circuit consisting of primitive elements such as combinatorial logic gates (AND, OR, NOT, NAND, NOR, etc.) and sequential logic gates (flip flops, latches, memories) is modified to meet its timing requirements.
STANAG3350 video is supplied as a component RGB signal with timing similar to a corresponding civilian composite video standard such as NTSC, PAL, or RS-343. Only the vertical and carrier frequency of the signal are defined by the standard, the horizontal resolution can vary from one implementation to another and still satisfy the STANAG 3350 ...
