Being tied to the code editor is the entire point, otherwise I would have just used GTKwave. Integrating it into the code editor - specifically VScode allows me to support terminal links (instance paths and timestamps from sim logs), first

I'm working on a digital waveform viewer for VScode. I started it back when I used to work for an FPGA company, and needed to debug soft CPUs. Now it's starting to rival the proprietary software. I should probably do a show HN at

Another point about HFT - They're mostly using FPGAs (some use custom silicon) which means that they have much tighter control over how DRAM is accessed and how the memory controller is configured. They could implement this in hardware

Yeah, I was a bit surprised that the author didn't mention that facet of Open AI. It did mention infrastructure goals, but the reality is that Open AI's infrastructure spending commitments have inflated the stock prices of quite a

Crazy idea, but maybe change the rules of Show HN so that you are required to include in the headline how long you have been working on the project. As an example, something like: Show HN: My Project - A description for my vibe coded projec

You have to understand the people in the article are execs from the chip EDA (Electronic Design Automation) industry. It's full of dinosaurs who have resisted innovation for the past 30 years. Of course they're going to be blowing

Kind of a wild idea, but have you considered using this as a markup language for logic diagrams? I'm thinking something like mermaid - https://mermaid.js.org/ While this might not be super useful for chip design, it is

As much as I love Zed, I am of the belief that VScode (and its derivatives) will remain the dominant build-your-own IDE for a really long time unless something like Zed can support web based extensions. I created a VScode extension for chip

Dating apps are a Skinner Box by nature. They give randomized reward in the form of likes and matches. If you're attractive, you're the product because you don't need premium service to get more dates. Give me Yelp for date s

Another one is custom CSS (though it doesn't look like positron does that.) You can change styling properties like spacing and weighting as well. I have a love/hate relationship with the VScode webview panels, but the message hand

Unfortunately socketed processors only really work with DDRx type DRAM interfaces. GPUs use GDDR and HBM interfaces, which are not ideal for sockets. In the case of HBM, you have 1024 data traces per DRAM chip, which would make the socket h

Love to see this at the top of HN! I haven't written anything with this language yet, but I have met some of the developers of this language. They're pretty great and they are doing a lot of really good work in the open source har

Not exactly. The name of the game with GDDR memory is "speed on the cheap." To do this, it uses a parallel bus with data rates pushed to the max. Not much headroom for things that could compromise signal integrity like socketed pa

As of recent, I have had this pet theory that there's a brilliance / stupidity spectrum, but if you go too far in one direction it loops back on itself. Some things are just so stupid that they're brilliant. I really like thi

Not malicious, but still selfish. It's important to remember that the copilot extensions are an extremely effective way of monetizing VScode. So it seems more like they're kind of compromising on their API usage rules in order to

Don't forget that the power rating of a laser pointer (unlike literally every other type of light you buy) is the output power, not the input power! More importantly, it's the output power of only the green laser! The 1064nm excit

As a hardware developer, I love seeing EDA tools getting YC's attention and resources. When hardware designers talk about how terrible EDA tools are though (myself included,) I find that it's a lot of the pot calling the kettle bl

Oh, interesting! I remember hearing rumblings that PAM4 was kind of a pain in GDDR6X. This makes sense. I still stand by my claim about PAM3 though.

> with the same latency I highly doubt that. With on-die ECC and the ridiculously complicated PAM3 encoding/decoding, I would bet that latency is going to increase over GDDR6.

by Lramseyer 3y ago
Just got my hands on the spec and read through it for a bit. A couple interesting things I noticed that were notable changes from GDDR6. Obviously, the big news is PAM3 signaling, and on die ECC. These aren't all that new, as NVIDIA&#x

Controllers kind of do that. At the end of the day, it's what makes designing a memory controller so difficult (and I'm not even talking about the Phy, those things are straight up cursed!) We see these eye popping numbers for max

The thing is, the PCIe EP on the FPGAs uses the general purpose SerDes that are routed to the PCIe controller in the bitstream. So if you were to load a different malicious bitstream (which is admittedly a challenge in it's own regard)

You're attaching your design to the Mac layer inside the FPGA, not to the IO pins, so it's the PIPE interface or something similar that you would need to communicate with. And yes, you can bypass the PCIe or Ethernet controller on

The pattern I have observed in my friends and myself (when I was on dating apps) goes something like this: We get matches, some of those matches flake, don't respond, or don't pan out into anything. So we mitigate that emotional r

One thing that doesn't sit well with me about most dating apps is that they operate under the paradigm where "If you're attractive, you're the product, not the customer" If you're getting likes, or swipes, or m
