ATF22V10 DEVELOPMENT BOARD

PCB and firmware to program the ATF22V10 SPLD.

Compilation

For flashing the SPLD, we make use of galette. This repository is available in this folder as submodule, which you need to sync via

git submodule update --init --recursive

Next, to create the galette executable, follow the instructions below.

sudo apt install build-essential cargo rustup
cd galette/src
cargo build --release

The executable resides in ./target/release/galette.

Creating JED files

Construct a .pld file and move to the folder in which the file resides. Next, run

../../galette/target/release/galette example.pld

For some of the examples provides under plds, there are also Makefiles available.

Next, the resulting .jed file can be flashed onto the ATF22V10 chip using a compatible chip flasher such as the TL866II+.

Warning

According to the datasheet, the ATF22V10 chips have a limited number (i.e. 100) of erase/write cycles.

Tip

For verification purposes, deselect Encrypt Chip.

[!NOTES]
The ATF22V10 has weak sourcing capacity, meaning it can only drive about 4mA of current. It however has strong sinking capacity.
