Aldec Active-HDL 12.0.118.7745

Aldec, Inc., a pioneer in mixed HDL language simulation and hardware-assisted verification for FPGA and ASIC designs, has enhanced Active-HDL to support new features within VHDL-2019 (IEEE 1076-2019). These features simplify the language, lift certain restrictions that were present in earlier versions and introduce new application programming interfaces (APIs).

Support has also been added for release 2020.08 of the open source VHDL verification methodology (OSVVM).

Support for OSVVM 2020.08 gives users of Active-HDL access to the free and open-source methodology’s new requirements tracking, updated scripting, AXI4 full verification components, and model independent transactions.

The latest version of Active-HDL also sees SystemVerilog enhancements that include initial support for multidimensional arrays of instances, preliminary support of unresolved user-defined nettypes, and preliminary support for unique constraints.

Several non-standard extensions to SystemVerilog are present in the latest release of Active-HDL too. These include allowing variable type outputs of clocking blocks to be driven by a continuous assignment, allowing the use of foreach loops iterating over the elements of a subarray, and assigning a virtual interface with a modport to a virtual interface without a modport.


Active-HDL is an integrated environment designed for development of VHDL, Verilog/SystemVerilog, EDIF, and SystemC designs. It comprises of several design entry tools, HDL/SystemC compiler, single simulation kernel, several standard and advanced debugging tools, graphical and textual simulation output viewers, and many auxiliary utilities designed for easy management of designs, resource files, and libraries as well as built-in interfaces that allow running simulation, synthesis, or implementation locally or on remote computers, controlling revision of source files, or communicating with third-party tools that provide simulation models.

In addition, Active-HDL provides a set of powerful wizards which facilitate creation of new workspaces, designs or design resources including VHDL, Verilog, SystemC source files, block or state diagrams, testbenches, etc.

Most operations that you perform from the graphical user interface can be also invoked through the commands of the Active-HDL macro language. By writing your own macros, you can significantly improve testing and automate design processing. Active-HDL also provides scripting engines for Perl and Tcl/Tk. By creating user-defined scripts, you can enhance Active-HDL design environment by adding additional windows, extending the macro language, and providing interfaces to external tools and software products.

The Active-HDL suite also includes VSimSA, a standalone VHDL/Verilog/SystemVerilog/EDIF/SystemC simulation environment designed for batch processing. Functionally, VSimSA is entirely independent of Active-HDL. What distinguishes VSimSA from Active-HDL is the lack of a graphical user interface (GUI). VSimSA commands and programs are issued and controlled exclusively from a command-line, which is especially useful in an automated design testing.

Active-HDL 12 provides many new features and enhancements that simplify team-based design, increase design productivity and the speed of behavioral, RTL, and timing simulation of VHDL, Verilog, SystemC, SystemVerilog and EDIF projects.

Active-HDL 12 is offered in an FPGA vendor-independent edition and supports all leading C/HDL synthesis and implementation tools which can be started directly from the Active-HDL environment. The installation program automatically installs all system libraries and allows selecting both target FPGA technology and vendor-specific libraries required for running HDL simulation.
