24 alternatives to Parameterized PWM controller in VHDL
Digital outputs can either go ON or OFF. Analog signals, on the other side, can smoothly assume multiple values in a range. There is a technique that emulates analog behavior with a digital output. That technique is PWM, namely, Pulse Width Modulation. It can be implemented as pulses with varying &#
This is a VHDL implementation of a parameterized PWM controller that generates pulse width modulation signals. PWM emulates analog behavior on digital outputs by varying the duration of high and low pulses. The… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Parameterized PWM controller in VHDL launched in 2018; newer entries below may have overtaken it.

This is a little toy project of mine that lets you simulate digital logic graphs. It was inspired by Minecraft's Redstone and the Piet esolang. It's got some serious drawbacks-- you write circuits as PNGs and simulate them with a Python interface. It's slow to run and slow to experiment with. And it is certainly difficult to use for people with any kind of color blindness. But despite that, I hope this can still be a fun toy!

Modo▲148I’ve built hardware projects for years, and the gap between “I want X” and “parts ordered, files ready to print” always took weeks. Modo compresses that. Describe what you want (e.g. “a portable CO2 monitor with a display and buzzer”) and it generates: - A bill of materials with real components (MPNs, not hallucinated parts) - A printable enclosure generated from actual part dimensions - Wiring diagrams, firmware boilerplate, and assembly instructions - Design validation (power budget, pin conflicts, mechanical fit) Everything streams in real time as each phase completes. The key idea is…

Simple KVM lets you control multiple PCs from one mouse, keyboard and monitor(s). It is similar to Haimgel's display-switch (https://news.ycombinator.com/item?id=29608967), but it provides a GUI which hopefully makes it a bit easier to set up. It also supports hotkeys which effectively lets you alt+tab between computers. I was surprised by the star-to-download ratio (55:400) on GitHub, so I thought I'd post it here as it might be useful to someone. Feedback welcome! Thanks, Fidel

Hi HN, I made some animations of the most important kinds of transistors using my semiconductor simulation, details of which are on the page. I tried to make the visuals as realistic as possible while also aiming for clarity. If you want to go beyond the charge carriers and look at, for example, the electric field, you can do so in the simulation software. The desktop software also has less common devices like IBGTs and SCRs that have similar animations. The last thread about my software was posted here about a year ago: https://news.ycombinator.com/item?id=43942279

Hi! me and my friends together built an 8 bit CPU implemented in Logisim purely from scratch. The control unit of this system does not implement the generic microcode ROM or any kind of RAM. This was made purely from discrete logic gates and coded the system to run different programs. key features: Custom 16-instruction Harvard ISA, 8-bit fixed format, 4 general purpose registers Hardwired control unit built entirely from AND/OR gate logic matrix Dual-phase clocking to eliminate race conditions Bootstrap Control Unit that cold-boots via ROM-to-RAM transfer Early-exit conditional…

Hi, everyone. I created a note-taking website for electronics and circuits where you can draw circuit diagrams and write text notes at the same time. I am a Digital IC designer, and I self-study different types of analog and digital circuits a lot. However, I found a problem. Circuits have many different architectures and are hard to memorize due to numerous experiential tips. I want to document what I learn in my note app, but I found there is no method for me to easily draw circuit and block diagrams alongside text notes. This issue has bothered me for a long time, from my master's school…
