VHDL Simili - Version 3.1

 

Compare Standard vs. Professional Edition

VHDL Simili is a low-cost, yet powerful and feature-rich VHDL development system designed for the serious hardware designer. It includes a very fast VHDL compiler and simulator assembled into a powerful Integrated Development Environment and waveform interface. The compiler/simulator can be used with or without the graphical user interface (as batch tools). VHDL Simili Professional Edition adds advanced debugging and code-coverage capabilities. VHDL Simili development is currently available for FREE (intended for small designs and for students) or you can request a demo/trial license for the full version after downloading and installing the software.

Compiler/Simulator Features:

VHDL Simili is offered in Standard and Professional Editions (see "feature comparison page" for differences).

  • IEEE 1076-93 VHDL language compliant compiler/simulator (includes built-in standard libaries). -- also allows VHDL'87 style FILE declarations.
  • Incorporates ZEOS  technology for very fast and flexible compilations and simulations.
  • Support for IEEE packages (std_logic, numeric_std, numeric_bit, etc.).
  • Support for Vital 95/2000 (IEEE 1076.4) and SDF 2.1, 3.0 and 4.0 for back-annotation. of timing data.
  • Support for Synopsys libraries (std_logic_arith, std_logic_signed, std_logic_unsigned, etc.)
  • Accelerated versions of packages mentioned above.
  • TEXTIO redirection mechanism.
  • Support for 64-bit time, 64-bit user defined physical types and 64-bit floating point (real) numbers.
  • Choice of disabling acceleration of specific packages at runtime.
  • Platform support: Windows 2000/XP, Linux Redhat 7.1 or newer.
  • Compiler/Simulator designed so they can run in batch mode (perfect for running regressions).
  • Extremely fast compilation speeds (several thousands of lines per second).
  • Co-exists with other synthesis/verification products
  • Ships with pre-compiled or ready-to-be-compiled libraries for
  • IEEE Libraries (pre-compiled, accelerated)
  • Synopsys Libraries (pre-compiled, accelerated)
  • Actel Vital Libraries (Compilation scripts)
  • Altera Vital Libraries (Quartus compilation scripts or MAX+plus-II Version 9.21)
  • Atmel 40k, 6k libraries (Compilation scripts, documentation provided, IDS version 6.0)
  • Cypress Libraries (Compilation scripts, documentation provided, Warp version 5.2 and up)
  • Xilinx Libraries LogiBlox, UniSim and SimPrim (Compilation scripts, documentation provided)

Graphical User Interface Features:

  • Framework:
    • Multi-threaded user interface (GUI never freezes during time consuming tasks)
    • Tcl console with color-coded messages
    • History mechanism
    • Command log
    • Error tracking (including ASSERTs/REPORTs from VHDL)
    • User configurable colors and fonts.
    • Preference database (remembers a very large number of user preferences and settings from previous run)
    • Auto-load externally modified files (easier integration with other text editors, user can disable this)
    • Context sensitive menus throughout
  • Licensing:
    • Industry standard FLEXlm based licensing mechanism with Symphony EDA added enhancements to make license management as painless as possible
    • Graphical Licensing Management Wizard to step you through license fulfillment (even includes demo and free licenses)
    • Supports demo, node-locked and floating licensing policies
    • Automated license fulfillment -- You can be up and running in as little as 5 minutes (any time, any day) after downloading and installing the software
  • Project management:
    • Designed for handling hundreds of files in a single project (workspace) with ease
    • Manages multiple libraries in one workspace
    • Smart compile (built-in make)
    • Dynamic (continuous) automatic file ordering
    • Portable output file formats (between Unix and Windows)
    • Manage compiler options with ultimate flexibility (can be file specific or library specific or both)
    • Manage all your simulator options (acceleration, SDF settings, etc.)
  • Simulation/Waveform:
    • Multi-million vector capacity with small memory footprint
    • High performance waveform display -- super fast scrolling, zooming, painting, etc.
    • Continuous waveform update (simulator does not have to stop to see waveforms)
    • Compressed waveforms to disk -- extremely small disk footprint
    • Drag and drop to waveform window to add new waveforms
    • Display values in Unsigned/Decimal/Hex/Octal/Binary/Symbolic/Analog
    • Display any VHDL signal type (including multi-dimensional arrays, enumerated types, records, real-numbers, etc.)
    • Display hierarchy/structure of your design
    • Signals/Variables display for any part of the hierarchy
    • Infinite number of user defined draggable markers (measurement anchors)
    • Load/save waveforms to disk
  • Debugging Features: (available in Professional Edition)
    • Breakpoints
    • Stop/continue from ASSERT/REPORT statements
    • Efficient Code-coverage with user-defined exceptions and HTML/TEXT/Graphical reports
  • Language sensitive text editor:
    • Powerful text editor with infinite levels of undo/redo
    • Syntax highlighting
    • User configurable colors for keywords, comments, constants, etc.
    • Bookmarks, auto-indent, comment-block, un-comment-block, etc.
    • Even tolerates an external editor (emacs, vim, prism, etc.) gracefully.
