Who can recommend a getting started tutorial on FPGA?

Course on designing a digital system using OpenGL (version 2) Xia Yuwen: This is the basis of grammar. This is an electronic version.
Go deep into simple gameplay FPGA (with a CD) Wu houhang's video tutorial experience
Altera FPGA/CPLD design (basic) (version 2nd), which includes introduction to altera devices and the use of quartus
Advanced FPGA/CPLD design (advanced) (2nd)
Design and verification: Hu Jihua, and Wang Cheng: This is a good book. It's good to read the electronic version.
By Kriz, advanced FPGA design structure, implementation and optimization, Meng xianyuan translation is said to be very advanced.
