Did You Know YoSys Knows VHDL Too?

We’ve been fans of the Yosys / Nextpnr open-source FPGA toolchain for a long while now, and like [Michael] we had no idea that their oss-cad-suite installer sets up everything so that you can write…

Making USB Blaster Clones Work For Linux

The last time we checked in with [Downtown Doug Brown], he had some cheap Altera USB Blaster clones that didn’t want to work under Linux. The trick at that time was to change the device&#8217…

Tiny Tapeout 3: Get Your Own Chip Design To A Fab

Custom semiconductor chips are generally big projects made by big companies with big budgets. Thanks to Tiny Tapeout, students, hobbyists, or anyone else can quickly get their designs onto an actua…

Ztachip Accelerates Tensorflow And Image Workloads

[Vuong Nguyen] clearly knows his way around artificial intelligence accelerator hardware, creating ztachip: an open source implementation of an accelerator platform for AI and traditional image pro…

Using VHDL To Generate Discrete Logic PCB Designs

VHDL and Verilog are hardware description languages, used to describe and define logic circuits. They’re typically used to design ASICs and to program FPGAs, essentially using software to def…

Capacitive Touch Controller For FPGAs

Most projects that interface with the real world need some sort of input device. Obviously this article is being written from a standardized “human interface device” but when the comput…

Custom RISC-V Processor Built In VHDL

While ARM continues to make inroads into the personal computing market against traditional chip makers like Intel and AMD, it’s not a perfect architecture and does have some disadvantages. Wh…
