Development Software

To write your own VDHL-code you can use the ispLEVER Classic Software from Lattice ([1]

You also need a programmer (e.g. HW-USBN-2A from Lattice) to deploy the VHDL-Code on your PLD.

After installing the software and the drivers for your programmer you can start a new project.

Programming example

You can find a demo-project

For the demo-project you need an additional hardware.

You can find the schematic here:media:SRAM.pdf
