BFMs are often used as reusable building blocks to create simulation test benches, in which the bus interface ports of a design under test are connected to appropriate BFMs. Another common application of BFMs is the provision of substitute models for IP components: Instead of a netlist or RTL design of an IP component, a 3rd party IP supplier ...
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.
Stimulus is provided to exercise each line in the HDL code. A test-bench is built to functionally verify the design by providing meaningful scenarios to check that given certain input, the design performs to specification. A simulation environment is typically composed of several types of components:
To simulate an HDL model, an engineer writes a top-level simulation environment (called a test bench). At minimum, a testbench contains an instantiation of the model (called the device under test or DUT), pin/signal declarations for the model's I/O, and a clock waveform.
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 ...

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.
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.
