Tufts ES 4 lab 0 from Spring 2021 (when labs were offered in a hybrid format). This is an introduction to synthesizing a basic design using icestudio and implementing it on the UPduino 3.0 which uses a Lattice iCE40 UP5K FPGA.
Materials for the current iteration of the course are at www.ece.tufts.edu/es/4/

Nice job! Thanks a lot! 😀️ Just wanted to point out that the workflow can be simplied a little bit just by pressing only the upload option. It will automatically build the design and upload it. The workflow could be: edit your circuit, click on upload. Edit again, click on uplaod...

Probably, the FPGA output buffer would burn out before the LED.

I've just started using FPGA's and your video series will be a great help. I don't get the 4 pulldown menus on my version 0.10-rc1

Do you mean the "Basic", "Bit", "Logic", and "Mux" pulldowns? To get the part menus, you may need to load a "collection" (Tools > Collections > Add). I haven't used the most recent version of icestudio, so this may have changed.

Hi Steven, thanks for getting back to me - I'll try searching some more options

It's looks like Lattice has embraced (or at least not opposed) the open-source synthesis / place-and-route tools that generate Lattice bitstreams! Any thoughts on how these open-source tools (ex. IceStudio / SymbiFlow / YosysHQ ) compare to the commercial offerings? For example, can the older (2004) Lattice Products listed on the website (ex. Design Software > 1553 Encoder/Decoder ) be freely-downloaded, and synthesized with either tool? I'm interested in starting with a working IP, going thru the design flow software, to finally testing on hardware!

The open-source toolchains only work for the iCE40-series parts, as far as I know. There is active work on the ECP5 and other parts, but they're not fully supported. In terms of synthesizing Verilog/VHDL to hardware, the open-source toolchain is just as good if not better than the commercial tools (or at least, you're a lot more likely to get support from the open-source community than from Lattice as a free user). But in terms of integrating pre-packaged IP, doing power analysis, and other more specialized stuff, the Lattice tools have the advantage.
