Tool for generating multi-purpose makefiles for FPGA projects.
Main features:
makefile generation for: fetching modules from repositories simulating HDL projects synthesizing HDL projects synthesizing projects remotely (keeping your local resources free) generating multi-vendor project files (no clicking in the IDE!) many other things without involving make and makefilesHdlmake supports modularity, scalability, revision control systems. Hdlmake can be run on any Linux or Windows machine with any HDL More info at the Wiki page

wbgen2 is a tool for generating VHDL/Verilog cores which implement Wishbone bus slaves with certain registers, memory blocks, FIFOs and interrupts. The input is a C-like syntax file with an abstract description of what do we want to have in the slave. As a result, we get:
- Automatically allocated memory layout
- VHDL/Verilog code for the slave module
- C header files for driver development - Nice HTML documentation

This project defines data structures, to be embedded in the FPGA memory address space, to enumerate the devices that have been synthetized in the current design. The same structure is also used as a simple flash file system. AKA Self-Describing Bus (SDB) Specification for Logic Cores. The layout is simple enough to be parsed both by the host and by the internal soft-core, if any.
The documentation is public, and related code is GNU GPL licensed.

Software support for the SPEC board, including kernel and user-space Linux code. The package also include the fmc-bus driver, which is expected to be used by other carriers as well.

A software framework for Linux device drivers aimed at supporting controls and data acquisition hardware. ZIO supports sub-nanosecond timestamps, block-oriented input and output and transport of meta-data with the data samples. Users can change the buffer type and trigger type associated with a device at run time, and all of devices, triggers and buffers are easily implemented as add-on modules.
The PF_ZIO implementation, currently in beta status, implements a network interface to the ZIO transport, which allows each I/O channel to generate or receive network frames. Applications see the network of devices and can talk with several of them from the same socket. We support SOCK_STREAM, SOCK_DGRAM and SOCK_RAW.
