The Hamburg VHDL Archive - lots of stuff here including a good look at libraries and packages.
Since the early 80's our institute has been member of different research activities and projects dealing with system- and VLSI-design.
A VHDL tutorial with good examples and links to reference and related material.
HDL (Hardware Description Language) based design has established itself as the modern approach to design of digital systems, with VHDL (VHSIC Hardware Description Language) and Verilog HDL being the two dominant HDLs.

Configuring Spartan-II FPGAs from Parallel EPROM
Many FPGA users prefer to store configuration data on parallel PROMs because they are available in greater storage capacities than serial PROMs. A parallel PROM stores data as an addressed byte which is accessed by an address bus.
Overview of Boundary Scan and the Boundary Scan Interface in Spartan-2 FPGAs
Developed to test interconnect between chips on PCB � Originally referred to as JTAG (Joint Test Action Group) � Uses scan design approach to test external interconnect � No-contact probe overcomes problem of �in-circuit� test.
