  2. Bus functional model - Wikipedia

    en.wikipedia.org/wiki/Bus_Functional_Model

    A BFM is typically implemented using hardware description languages such as Verilog, VHDL, SystemC, or SystemVerilog. Typically, BFMs offer a two-sided interface: One interface side drives and samples low-level signals according to the bus protocol. On its other side, tasks are available to create and respond to bus transactions.

  3. VHDL - Wikipedia

    en.wikipedia.org/wiki/VHDL

    VHDL source for a signed adder. VHDL (VHSIC Hardware Description Language) is a hardware description language that can model the behavior and structure of digital systems at multiple levels of abstraction, ranging from the system level down to that of logic gates, for design entry, documentation, and verification purposes.

  4. Hardware description language - Wikipedia

    en.wikipedia.org/wiki/Hardware_description_language

    An HDL simulator — the program that executes the testbench — maintains the simulator clock, which is the master reference for all events in the testbench simulation. Events occur only at the instants dictated by the testbench HDL (such as a reset-toggle coded into the testbench), or in reaction (by the model) to stimulus and triggering events.

  5. Specman - Wikipedia

    en.wikipedia.org/wiki/Specman

    To simulate an e-testbench with a design written in VHDL/Verilog, Specman must be run in conjunction with a separate HDL simulation tool. Specman is a feature of Cadence's new Xcelium simulator, where tighter product integration offers both faster runtime performance and debugs capabilities not available with other HDL simulators.

  6. Logic synthesis - Wikipedia

    en.wikipedia.org/wiki/Logic_synthesis

    Using high-level synthesis, also known as ESL synthesis, the allocation of work to clock cycles and across structural components, such as floating-point ALUs, is done by the compiler using an optimisation procedure, whereas with RTL logic synthesis (even from behavioural Verilog or VHDL, where a thread of execution can make multiple reads and ...

  7. List of HDL simulators - Wikipedia

    VHDL-1987,-1993,-2002,-2008, V2001, SV2005, SV2009, SV2012, SV2017: The original Modeltech (VHDL) simulator was the first mixed-language simulator capable of simulating VHDL and Verilog design entities together. In 2003, ModelSim 5.8 was the first simulator to begin supporting features of the Accellera SystemVerilog 3.0 standard. [1]

  8. Test bench - Wikipedia

    en.wikipedia.org/wiki/Test_bench

    A test bench or testing workbench is an environment used to verify the correctness or soundness of a design or model.. The term has its roots [citation needed] in the testing of electronic devices, where an engineer would sit at a lab bench with tools for measurement and manipulation, such as oscilloscopes, multimeters, soldering irons, wire cutters, and so on, and manually verify the ...

  9. MyHDL - Wikipedia

    en.wikipedia.org/wiki/MyHDL

    MyHDL [1] is a Python-based hardware description language (HDL).. Features of MyHDL include: The ability to generate VHDL and Verilog code from a MyHDL design. [2]The ability to generate a testbench (Conversion of test benches [3]) with test vectors in VHDL or Verilog, based on complex computations in Python.
