![]() It's done with entirely open source tools (the IceStorm toolchain) and most of the magic is due to the representation in Hardware Description Language, i.e. > Validation of design rules & connectivity ![]() But you're actually programming a reusable and fairly inexpensive FPGA. In the parlance of a silicon fab, you've gone through a "spin". Each time you add a new input or a gate, or an LED, hit "Build" and "Upload". Explore, build and create, but most importantly, get near-instant feedback in testing your real hardware design. Icestudio provides circuit simulation (for digital circuits) that's arbitrarily scalable. They are digital logic: Gates, multiplexers, counters, registers, adders, multipliers and more. Indexĭevices by type and name What are the 7400-series TTL chips? This is the way to go if you wish to set the parameters for #bits, #inputs per gate, #blocks in a device. There's a variety of ways to provide inputs and view outputs but no need for actual parts, wires or power supply.Īlternatively, you can download an individual device ( 74xx.v file) and use it in your own simulation in Verilog. ![]() Place and wire up your components, run and test the result. In Icestudio, go to Tools > Collections > Add and select the downloaded. ![]() The easiest way to use these devices is download the collection and open it in the Icestudio design environment.
