System on Chip
Development status: Stable
WishBone Compliant: Yes
- add verilog output
- when data bus size is 8 bits the script generates wishbone sel signals which are of no use
- GUI for easy startup
- supports both shared bus and csorrbarswitch topology
- design tested in HDL simulator and in FPGA (ALTERA C12)
- current design only support VHDL output
The intention is to provide an easy way to create and change a system based on the WISHBONE bus. The user shall be able to try different configurations to achieve an area/performance optimized design.
WISHBONE builder is a script which generates a wishbone interconnect matrix in HDL. The user defines the functionallity of the wishbone bus in a text file or via a GUI. The tools then generates the HDL implementation.
The core supports both shared bus and crossbar switch implementations.
To run the WISHBONE builder you must have installed PERL. A windows executable can be found at http://www.activestate.com/. In Linux PERL is usually installed with the system. The GUI uses a PERL module called Tk. Tk can be found at CPAN, http://www.cpan.org/.
