Ikos NSIM-64 Hardware simulation accelerator. In integrated circuit design, hardware emulation is the process of imitating the behavior of one or more pieces of hardware (typically a system under design) with another piece of hardware, typically a special purpose emulation system.
It has a few features, but this release has enough for a VLSI student to use and learn Verilog. Supports only behavioral constructs of Verilog and minimal simulation constructs such as 'initial' statements. VeriWell: GPL2: Elliot Mednick: V1995: This simulator used to be proprietary, but has recently become GPL open-source.
Behavioral simulation – high-level simulation of a design's architectural operation, accurate at cycle-level or interface-level. Hardware emulation – Use of special purpose hardware to emulate the logic of a proposed design. Can sometimes be plugged into a system in place of a yet-to-be-built chip; this is called in-circuit emulation.
VHDL analyzer, compiler, and simulator. [12] Icarus Verilog *BSD, Linux, Mac: GPL-2.0-or-later: Verilog simulator Verilator: Posix: LGPL-3.0-only or Artistic-2.0: Verilator is the fastest free Verilog HDL simulator. It compiles synthesizable Verilog into cycle accurate C++ or SystemC code following 2-state synthesis (zero delay) semantics.
Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions or billions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit (metal oxide semiconductor) chips were developed and then widely adopted, enabling complex semiconductor and telecommunications technologies.
This step brings a lot of uncertainties because the real hardware is normally not as ideal as the simulation model. The differences between real world and simulation are a major reason why emulation is used in hardware design. Generally the simulation and emulation environment are two independent systems. Semulation is a symbiosis of both methods.
Symbolic simulation is a form of simulation where many possible executions of a system are considered simultaneously. This is typically achieved by augmenting the domain over which the simulation takes place. A symbolic variable can be used in the simulation state representation in order to index multiple executions of the system. [1]
In 2000, EVE was founded in France. [1]In 2002, EVE launched its flagship ZeBu's first emulation product and SystemC support. [2]In May 2006, EVE introduced a communication link to SystemVerilog simulation, SystemVerilog assertion support, and a register transfer level compiler for mapping an ASIC or System-on-a-chip (SOC) design into ZeBu's arrays of FPGAs.
