VHDL-1993,-2002 (subset),-2008 (subset), [2] V2001, V2005, SV2009, SV2012, SV2017: Xilinx Simulator (XSIM) comes as part of the Vivado design suite. It is a compiled-language simulator that supports mixed language simulation with Verilog, SystemVerilog, VHDL and SystemC language.
ModelSim is a multi-language environment by Siemens [1] (previously developed by Mentor Graphics, [2]) for simulation of hardware description languages such as VHDL, Verilog and SystemC, and includes a built-in C debugger. [3] [2] ModelSim can be used independently, or in conjunction with Intel Quartus Prime, PSIM, [4] Xilinx ISE or Xilinx ...
The Vivado High-Level Synthesis compiler enables C, C++ and SystemC programs to be directly targeted into Xilinx devices without the need to manually create RTL. [ 15 ] [ 16 ] [ 17 ] Vivado HLS is widely reviewed to increase developer productivity, and is confirmed to support C++ classes, templates, functions and operator overloading.
Initially, Verilog and VHDL were used to document and simulate circuit designs already captured and described in another form (such as schematic files). HDL simulation enabled engineers to work at a higher level of abstraction than simulation at the schematic level, and thus increased design capacity from hundreds of transistors to thousands.
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.
DSP Builder, a tool that creates a seamless bridge between the MATLAB/Simulink tool and Quartus Prime software, so FPGA designers have the algorithm development, simulation, and verification capabilities of MATLAB/Simulink system-level design tools
High-level synthesis (HLS), sometimes referred to as C synthesis, electronic system-level (ESL) synthesis, algorithmic synthesis, or behavioral synthesis, is an automated design process that takes an abstract behavioral specification of a digital system and finds a register-transfer level structure that realizes the given behavior.
Since 2012, Xilinx ISE has been discontinued in favor of Vivado Design Suite that serves the same roles as ISE with additional features for system on a chip development. [8] [9] Xilinx released the last version of ISE in October 2013 (version 14.7), and states that "ISE has moved into the sustaining phase of its product life cycle, and there are no more planned ISE releases."
