=== The smallest FPGA ===

[[https://www.digikey.com/en/products/detail/microchip-technology/VERYVERILOG/29020656]]: $13.31 for a tiny, tiny programmable logic chip.

[[https://www.digikey.com/en/products/base-product/microchip-technology/150/PIC16F13145/733403]]: The raw chips for the above, cost a dollar or two.

=== Learning ===
[[https://byu-cpe.github.io/ComputingBootCamp/tutorials/vivado_tcl/| BYU computing Boot Camp]]: Better than nothing, but still has holes.

[[https://community.element14.com/technologies/fpga-group/b/blog/posts/the-art-of-fpga-design---post-8 | The Art of FPGA Design]]: Specifically about delay blocks, but has other useful tidbits.

[[https://fpgacpu.ca/fpga/index.html | FPGA Design Elements]]

[[https://zipcpu.com/blog/2017/06/02/design-process.html| FPGA Design Process]]: Also has a bunch of other useful tutorials, but is beyond intro level.

[[https://vanhunteradams.com/DE1/Mandelbrot/Mandelbrot.html|Mandelbrot lab]]: Base site also has useful stuff

[[https://people.ece.cornell.edu/land/courses/ece5760/DE1_SOC/HPS_peripherials/Examples_version_18.html|Quartus examples]]: From Cornell ECE5760

[[https://people.ece.cornell.edu/land/courses/ece5760/Altera_cookbook/cookbook/| Altera Cookbook]]:Also from Cornell
