anybody write a tolerable to use shim for vhdl or verilog yet having to write c# programs to emit dozens of lines of boilerplate is getting really tedious

compounded by the no systemverilog issue, of course

and the poverty-tier modelsim license, restricted to one hdl type at a time, hope those opencores vhdl blocks work

Bloody posted:anybody write a tolerable to use shim for vhdl or verilog yet having to write c# programs to emit dozens of lines of boilerplate is getting really tedious I've been too busy with work stuff to do more than shoot the poo poo about writing a Lisp HDL that outputs Verilog. (plus you'd have to use Lisp to use it. and my employer would have to sign off for me to share it…) instead of writing c# to emit boilerplate though, could use use the T4 template system or something? seems like that might be a better fit for just expanding out boilerplate, and it's part of Visual Studio too.

If you have 8 bi-color (red/green) LEDs (and assume that yellow is off-limits because it's a cheap piece of poo poo from China and green is weaker than red so red+green=red) and you need to indicate a percentage change from, say, -3% to +3%, where -1%-+1% is the most common swing (think stock market) how would you do so?

i would arrange them in a bar like thus x x x x x x x x and i would make the left four red only and the right four green only i would indicate zero by turning nobody on i would indicate +/-0.5% with the inner pair from there i would go +/-1, +/-2, +/-3, turning on additional lights

or i'd get the yellow mode working, throw one out, and use yellow as 0 and then +/- 1/2/3

Bloody posted:i would arrange them in a bar like thus that is way too coarse imo. I want it to be kinda like logarithmic so that everyday swings are noticeable e: dunno if I can get yellow working. there is a resistor network I could potentially replace with some more sensible values but I am not sure that will happen e: this is what I'm working with http://www.dx.com/p/8x-digital-tube-8x-key-8x-double-color-led-module-81873 sleepy gary fucked around with this message at 20:28 on Mar 7, 2015 |

project +/- 3.0 to +/- 255, display binary value in green > 0 in red <0

you could use all 8 and show positive values like this g g g . . . . . and negative values like this . . . . . . r r (it's color-blind-friendly!) and use pwm to scale the intensity of the outermost light for fractions, or even just blink it logarithmic may be good anyway e: blinking is annoying because it attracts attention but it would look cool if the value is moving quickly because it's like blink blink blink blink blinkblinkblinkblink *solid*, next light starts blinking suffix fucked around with this message at 20:46 on Mar 7, 2015 |

and also get the yellow working so you don't have the semipredicate problem ("is this showing zero or did the board burn out?")

Sigmoid and 1-sigmoid for outputs green and red and offset/scale it so that your poorly defined sample space is in it and it isnt just red all the time

I decided on 0.1 0.25 0.33 0.5 0.75 1 2 3 because its very human readable that way

I don't know how you think you can judge who I am because I said that I raped an electrical interface on a small computer. I think you have a lovely attitude. But, in all honesty, I'm sorry for the derail (not for what I said). I didn't realize this was that kind of a thread, so I'll see myself out.

I really do apologize, but put it in sh/sc if you don't want people to gently caress around. I don't think yospos should be too serious. Sorry, everyone.

if you're too bereft of vocabulary and must turn gauche to explain a simple concept you're not retreating from "too serious"
