From EET.com: "An open-source 'design organization' tool created
by Kevin Hubbard, an ASIC designer at Siemens Ultrasound, promises to
help manage large chip design projects without the overhead of
commercial, graphically oriented tools. Called ChipVault, the offering
provides Verilog or VHDL hierarchical file organization, revision control,
issue tracking, hierarchy viewing, block instantiation and hooks for
launching EDA tools."
