Xilinx ISE[1] (Integrated Synthesis Environment)[2] is a software tool produced by Xilinx for synthesis and analysis of HDL designs, enabling the developer to synthesize ("compile") their designs, perform timing analysis, examine RTL diagrams, simulate a design's reaction to different stimuli, and configure the target device with the programmer.

Vivado[edit]

The Vivado Design Suite was introduced in April 2012, and is an integrated design environment (IDE) with a system-to-IC level tools built on a shared scalable data model and a common debug environment. Vivado includes electronic system level (ESL) design tools for synthesizing and verifying C-based algorithmic IP; standards based packaging of both algorithmic and RTL IP for reuse; standards based IP stitching and systems integration of all types of system building blocks; and the verification of blocks and systems.[3] A free version WebPACK Edition of Vivado provides designers with a limited version of the design environment.[4]

The Vivado Simulator is a component of the Vivado Design Suite. It is a compiled-language simulator that supports mixed-language, TCL scripts, encrypted IP and enhanced verification.

Vivado is an IP and system-centric design software, and supports newer high capacity devices, and speeds the design of programmable logic and I/O.[5] Vivado provides faster integration and implementation for programmable systems into devices with 3D stacked silicon interconnect technology, ARM processing systems, analog mixed signal (AMS), and many semiconductor intellectual property (IP) cores.[6]

Vivado is targeted at Xilinx's larger FPGAs, and is slowly replacing ISE as their mainline tool chain. As of 2014, Vivado covers Xilinx's mid-scale and large FPGAs, and ISE covered the mid-scale and smaller FPGAs and all CPLDs.

The Xilinx ISE is a design environment for FPGA products from Xilinx, and is tightly-coupled to the architecture of such chips, and cannot be used with FPGA products from other vendors.[2] The Xilinx ISE is primarily used for circuit synthesis and design, while the ModelSim logic simulator is used for system-level testing.[7][8] Other components shipped with the Xilinx ISE include the Embedded Development Kit (EDK), a Software Development Kit (SDK) and ChipScope Pro.[9]

User Interface[edit]

The primary user interface of the ISE is the Project Navigator, which includes the design hierarchy (Sources), a source code editor (Workplace), an output console (Transcript), and a processes tree (Processes).[2][10]

The Design hierarchy consists of design files (modules), whose dependencies are interpreted by the ISE and displayed as a tree structure.[2] For single-chip designs there may be one main module, with other modules included by the main module, similar to the main() subroutine in C++ programs.[2] Design constraints are specified in modules, which include pin configuration and mapping.[2]

The Processes hierarchy describes the operations that the ISE will perform on the currently active module.[2] The hierarchy includes compilation functions, their dependency functions, and other utilities.[2] The window also denotes issues or errors that arise with ecah function.[2]

The Transcript window provides status of currently running operations, and informs engineers on design issues.[2] Such issues may be filtered to show Warnings, Errors, or both.[2]

Simulation[edit]

System-level testing may be performed with the ModelSim logic simulator, and such test programs must also be written in HDL languages.[2] Test bench programs may include simulated input signal waveforms, or monitors which observe and verify the outputs of the device under test.[2]

ModelSim may be used to perform the following types of simulations:[7]

  • Logical verification, to ensure the module produces expected results
  • Behavioural verification, to verify logical and timing issues
  • Post-place & route simulation, to verify behaviour after placement of the module within the reconfigurable logic of the FPGA

Synthesis[edit]

Xilinx's patented algorithms for synthesis allow designs to run upto 30% faster than competing programs, and allows greater logic density which reduces project costs.[11]

Also, due to the increasing complexity of FPGA fabric, including memory blocks and I/O blocks, more complex synthesis algorithms were developed that separate unrelated modules into slices, reducing post-placement errors.[11]

IP Cores are offered by Xilinx and other third-party vendors, to implement system-level functions such as digital signal processing (DSP), bus interfaces, networking protocols, image processing, embedded processors, and peripherals.[11] Xilinx has been instrumental in shifting designs from ASIC-based implementation to FPGA-based implementation.[11]

Editions[edit]

The Subscription Edition is the licensed version of Xilinx ISE, and a free trial version is available for download.

The Web Edition is the free version of Xilinx ISE, that can be downloaded and used for no charge. It provides synthesis and programming for a limited number of Xilinx devices. In particular, devices with a large number of I/O pins and large gate matrices are disabled.

The low-cost Spartan family of FPGAs is fully supported by this edition, as well as the family of CPLDs, meaning small developers and educational institutions have no overheads from the cost of development software.

License registration is required to use the Web Edition of Xilinx ISE, which is free and can be renewed an unlimited number of times.
