FPGA: LUTs: A look inside

How does an FPGA look from the inside and how does it work? How is it that any digital circuit can be deployed on an FPGA? This tutorial presents the construction of an FPGA.

FPGA: Development Flow

The basic hardware development flow on an FPGA. The tutorial is based on the Lattice iCE40 stick. Introduces the development flow using the open source tool chain and demonstrates using a blinky program.
