The VHDL and Verilog story

I put a blog entry up on the Oasys blog about their new release, which is the first to support VHDL. But a couple of people told me it was a nice recounting of history so I decided to put a more ...

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 in ...

Verilog versus VHDL (which is best?)

With regard to my recent blog on FPGA Prototyping Using Verilog Examples, someone emailed me to ask if there was a VHDL version (there isn't, as far as I know). The originator of the message also said ...

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 define ...

Facing Up To Today’s FPGA Verification Challenges

Today it is not unusual for FPGA users to have to deal with more than one language in their designs. At earlier stages of the design development it may be necessary to interface HDL simulation with ...

Challenges In Using HLS For FPGA Design

High-level synthesis (HLS) tools, which transform C/C++ source code to Verilog/VHDL, have been commercially available for over 15 years. HLS tools from FPGA vendors and EDA companies promise improved ...
