danstrother.com is a personal blog at danstrother.com about hardware and programming. Since 2012, 5 different Hacker News readers have linked it 5 times. The last post was in 2011, but the archive is still widely read.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for FPGA and hardware posts, such as one on inferring dual-ported RAM from HDL code, including the bugs encountered, and a 6502 synthesized on a Spartan 3 FPGA.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
robots, fpgas, tesla coils, photography, etcetera
What Hacker News says?
Here's an article (not written by me, just found by using google) that has an example how the VHDL/Verilog compiler infers to use a dual-ported SRAM from code that describes the behavior, including the bugs you'll encounter. http://danstrother.com/2010/09/11/inferring-rams-in-fpgas/

HN discussionYou can synthesize a 6502 on an FPGA just fine and can probably do it on this specific chip. There is a project I've seen ( https://danstrother.com/fpga-nes/ ) where someone did synthesize the 6502 along with the rest of the hardware on a Spartan 3 which does have more resources available to it. Looking at the utilization report in the comments on that page, it would be too much for this little Lattice chip. There a…

HN discussionThis fellow[0] designed a DDR2 interface, but I don't think he ever reported back whether or not it worked. Apparently he did it by hand in Eagle! To address your point about tools, I think you're right about the value aspect -- good tools cost money. But then again, does the average hobbyist need those kinds of tools? How much demand is there for, say, a 100 MHz open 'scope that costs a bit more than a Rigol? Ham e…
