When people were smart enough to use a 22-cent CD4017 instead of a 50-dollar FPGA to implement a 10-stage one-hot, people did that with schematics. Yeah, but you keep forgetting that my FPGA is doing more than just a counter. And what I do in my FPGA would take a whole rack full of SSI parts. Nowadays, folks aren't that smart. They buy and sell things that only barely work, like cellphones, for example. That's right, blame the technology and not the people doing the work. Put a few old timers who learned how to read schematics in a room, and, within minutes they all agree on what the schematic means. Put a dozen HDL experts in a room with the 1000-page listing that an 'E' sheet of schematics represents, in a room, and after two months, you'll have at least 13 opinions. How can you work with that? ... and the amount of schematic pages that are equivalent to a 1000-page HDL listing is, what, 1000? 5000? 10000? Who the hell can keep track of that, much less verify it? Give me a break. Really. It seems like the "experts" you've come across are not at advertised. There are tons of "experts" who do schematics which are completely inscrutable, and those "experts" probably don't even know how their own work functions after being away from it for a year. For trivial designs, a schematic may be easier. For larger stuff, give me an HDL any time. You DO realize that I was yanking your chain, and of course I got the expected response. -a |
