Hi all,

Just got this E40HX8k FPGA. My goal is to start off small and build an 8bit adder or something and then work up to building an interface for some old Soviet core memory I have.

Does anyone have any book recommendations?

My brain vomit questions un-researched questions:

  • Is Verilog like spice but text and not analog?
  • What happens if you try to load a sketch to your board which exceeds its capabilities what happens? Can you fry it?
  • How much do you need to account for the physical layout of the board? Do you need to “move” a small sketch closer to the memory to reduce latency or does the sketch have some compilation which squishes it into the best region?
  • is there a way to visualize the final physical sketch (where it is on the board) (probably board specific.

Anyway thanks!

Oh that’s cool I might have to start with someone else’s known working sketch then
