Amazing project to learn how FPGAs work. Not overkill with some high speed interfaces, but touches all problems: no easy division by 3 and 5, counters everywhere, no copy/paste solutions, no libraries with helpful functions. Though Xilinx ISE is obsolete, Vivado is the current tool.
- kens 9y agoUnfortunately Vivado doesn't support the Spartan 6 chip used by the Mojo board, just Spartan 7 and later.
- Posibyte 9y agoAs kens said, and to expand, Xilinx's Vivado doesn't support the Spartan 6, however they _do_ still fully support the Spartan 6 and continue to produce new chips. To support this, they've released a Virtualbox compatible image which runs Oracle Linux with ISE configured specifically to program Spartan 6 FPGAs.[1] [1]: https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/design-tools.html https://www.xilinx.com/support/download/index.html/content/x...
- jdswain 9y agoAnd the QFP Spartan 6 is the most powerful Xilinx FPGA that is hand solderable. Maybe not a concern if you are using an existing board or have a reflow oven, but for me that is a good reason not to go up to Spartan 7 or newer.
