This area of the FPGA Design space is where you'll find detailed reference material covering the following:

• FPGA Components – including processors, peripherals (Wishbone and non-Wishbone), virtual instruments, and OpenBus connectors.
• Constraint File Reference – the ins and outs of using constraint files to store implementation information, constraining a design to the required target device and PCB layout, while allowing the same design to be re-targeted quickly and easily.
• FPGA IO Standards Reference – covering all the IO standards supported in Altium Designer.
• Core Resource Usage. – provides detailed information about resource usage for a variety of pre-synthesized cores.
