VHDLAMS is a derivative of the hardware description language VHDL IEEE standard 1076 1993 . It includes analog and mixed signal extensions AMS in order to define the behavior of analog and mixed signal systems IEEE 1076.1 1999 . The VHDLAMS standard was created with the intent of enabling designers of analog and mixed signal systems and integrated circuits to create and use modules that encapsulate high level behavioral descriptions as well as structural descriptions of systems and components. ref Christen E., Bakalar K., VHDLAMS a hardware description language for analog and mixed signal applications ,Circuits and Systems II Analog and Digital Signal Processing, IEEE Transactions on see also Circuits and Systems II Express Briefs, IEEE Transactions on Volume 46, Issue 10, Oct. 1999, pp. 1263 1272. ref VHDLAMS is an industry standard modeling language for mixed signal circuits. It provides both continuous time and event driven modeling semantics, and so is suitable for analog, digital, and mixed analog digital circuits. It is particularly well suited for verification of very complex analog, mixed signal and radio frequency integrated circuits. Code example In VHDLAMS, a design consists at a minimum of an entity which describes the interface and an architecture which contains the actual implementation.

Verilog A is an industry standard modeling language for analog circuits. It is the continuous time subset of Verilog AMS . Verilog A was created out of a need to standardize the Spectre Circuit Simulator Spectre behavioral language in face of competition from VHDL an IEEE standard , which was absorbing analog capability from other languages e.g. MAST . Open Verilog International OVI, the body that originally standardized Verilog agreed to support the standardization, provided that it was part of a plan to create Verilog AMS &mdash a single language covering both analog and digital design. Verilog A was an all analog subset of Verilog AMS that was the first phase of the project. Unfortunately, there was considerable delay between the first Verilog A Programming language reference language reference manual and the full Verilog AMS , and in that time Verilog moved to the IEEE, leaving Verilog AMS behind at Accellera . Hence, the original goal of a single language standard is still to be achieved.

No footnotes date January 2012 Analog verification is a methodology for performing functional verification on analog, mixed signal and RF integrated circuits and System on a chip systems on chip . Discussion of analog verification began in 2005 when it started to become recognized that the analog portion of large mixed signal chips had become so complex that a significant and ever increasing number of these chips were being designed with functional errors in the analog portion that prevented them from operating correctly. Technical details Analog verification is built on the idea that transistor level simulation will always be too slow to provide adequate functional verification. Instead, it is necessary to build simple and efficient models of the blocks that make up the analog portion of the design and use those to verify the design. Those models are typically written in Verilog or Verilog AMS , but could also be written in VHDL or VHDL AMS . However, simply using a simple functional model is not sufficient. It is also necessary to build a comprehensive self checking testbench, that thoroughly exercises the design and compare its response against a previously written specification for the design. Furthermore, this testbench should be applied in turn to both the model and the design. In this case, the design is represented with a transistor level schematic. If both the model and the design pass all tests, and if the testbench is comprehensive, then this confirms that the model is consistent with the design and that the design is consistent with the specification. Applying a comprehensive testbench to an entire analog functional unit such as an audio codec , power management unit, serdes , or RF transceiver, represented at the transistor level is impractical. So instead, the verification proceeds hierarchically. One first builds simple models and testbenches for individual blocks. The block level testbenches are used to confirm that models match the implementation of ... more details

infobox software name Incisive developer Cadence Design Systems operating system Cross platform genre Simulator license proprietary website http www.cadence.com products fv Pages default.aspx Cadence Functional Verification Incisive is a suite of tools from Cadence Design Systems related to the design and verification of ASIC s, SoC s, and FPGA s. Incisive is commonly referred to by the name NCSim in reference to the core simulation engine. In the late 1990s, the tool suite was known as ldv logic design and verification . Depending on the design requirements, Incisive has many different bundling options of the following tools class wikitable Tool command description NC Verilog ncvlog Compiler for Verilog 95, Verilog 2001 and SystemVerilog NC VHDL ncvhdl Compiler for VHDL 87, VHDL 93 NC SystemC ncsc Compiler for SystemC NC Elaborator ncelab Unified linker elaborator for Verilog, VHDL, and SystemC libraries. Generates a simulation object file referred to as a snapshot image . NC Sim ncsim Unified simulation engine for Verilog, VHDL, and SystemC. Loads snapshot images generated by NC Elaborator. This tool can be run in GUI mode or batch command line mode. In GUI mode, ncsim is similar to the debug features of ModelSim s vsim.
