GHDL - a VHDL simulator
GHDL is the leading open source VHDL simulator. *** Now on github.com/tgingold/ghdl *** We have binary distributions for Debian Linux, Mac OSX and Windows. On other systems, getting GHDL from here means downloading the current source package and building GHDL from source. Alternatively you can get the latest source version (warning : occasionally unstable!) by pulling a snapshot from the git repository.
ADMS is a code generator that converts electrical compact device models specified in high-level description language into ready-to-compile c code for the API of spice simulators. Repository migrated to: https://github.com/Qucs/ADMS For checkout do: git clone https://github.com/Qucs/ADMS.git
An operating system written in RTL
The Controlix operating system is written in RTL and is designed to be modular, synchronous, distributed, verifiable and retargetable.
A new 64-bit RISC platform, complemented by a set of development tools, standards specifications and synthesizable VHDL implementations.
Powerful Verilog Preprocessor. PLP stands for Perl Pre-processor. Perl is used as "control language" that is embedded in the Verilog code (or any other code) to generate code on the fly. It is used commonly as a Verilog pre-processor but can be used with any target/output language (C, C++, Java, VHDL, plain text etc)
Verilog Finite State Machine (FSM) Code Generator
SmGen is a finite state machine (FSM) generator for Verilog. On the other hand, it is not an FSM entry tool. The input is behavioral Verilog with clock boundaries specifically set by the designer. SmGen unrolls this behavioral code and generates an FSM from it in synthesizable Verilog. Clock boundaries are explicitly provided by the designer so there is good control on the expected timing
