When you think about hardware description languages, you probably think of Verilog or VHDL. There are others, of course, but those are the two elephants in the room. Do we …read more Continue reading Do We Need a New Hardware Description Language?
Before a chip design is turned from a hardware design language (HDL) like VHDL or Verilog into physical hardware, testing and validating the design is an essential step. Yet simulating …read more Continue reading Exploiting Hardware-Level Parallelism in the Manticore Hardware-Accelerated RTL Simulator
The list of requirements for hosting one of our weekly Hack Chats is pretty short: you’ve got to be knowledgeable, passionate, and above all else, willing to put those two …read more Continue reading Al Williams Tells All in the Logic Simulation Hack Chat
The best thing about field-programmable gate arrays (FPGAs), when you have a massively parallel application, is that everything runs in parallel. The worst thing about FPGAs, when you need a lot of stuff to happen in sequence, is that everything runs in parallel. If you have a multi-step computation, for …read more
Usually when writing emulation software for a system like the Game Boy, one makes sure to take as many shortcuts as possible in order to reduce the resources required for the emulation. This has however the unfortunate side-effect that it reduces the overall accuracy of the emulation and with it …read more

It used to be that designing hardware required schematics and designing software required code. Sure, a lot of people could jump back and forth, but it was clearly a different discipline. Today, a lot of substantial digital design occurs using a hardware description language (HDL) like Verilog or VHDL. These look like software, but as we’ve pointed out many times, it isn’t really the same. [Zipcpu] has a really clear blog post that explains how it is different and why.
[Zipcpu] notes something we’ve seen all too often on the web. Some neophytes will write sequential code using Verilog or …read more
