Have any designs made with JITX been certified as UL compliant, or FCC compliant to standards like radiated emissions, AC conducted emissions, spurious emission

Have any designs made with JITX been certified as UL compliant, or FCC compliant to standards like radiated emissions, AC conducted emissions, spurious emissions, etc.?
How well does this software do in creating board designs that meet common government compliance requirements?
- cushychicken 8y agoFollowon: why is DDR4 a problem for your software? Any luck with a DDR3 layout?
- DHaldane 8y agoDDR4 is an example case that's just not well automated yet. We've got the road map sketched out but it hasn't been a priority. We're optimizing our development for features that make us immediately more productive at designing boards. Thus far that has been things like solvers for power supplies and automated component selection. The special case stuff will come later, when it becomes a bottleneck.
- cushychicken 8y agoThat makes sense - a buck regulator is a lot of component selection. Do I read a "no" between the lines of my question regarding DDR3? I ask because that's a design segment you could automate to great effect. The DRAM is nearly always the riskiest part of an embedded processor design - so much so that many companies (even large ones in my experience) do not deviate from vendor generated reference designs.
- DHaldane 8y agoSorry, should have addressed that directly. We haven't run a job with memory routing through the tool. Your point about DRAM is well taken, and we'll hopefully have a job justifying that bring-up soon.
- cushychicken 8y agoThanks for following up. The concept looks great. I'm glad to see people working to automate some of the drudgery in EE CAD.
- patricksli 8y agoFor advanced designs with lots of compliance requirements, our tool isn't yet able to fully-automatically compute the final design. For these designs, the tool does the parts it can and leaves the rest to be handled by an engineer. We have an internal scoreboard that tracks how much of each job we successfully automate, and we steadily improve our algorithms to make progress on that.
- cushychicken 8y agoThat's a sensible concept. I like the scoreboard idea. Are you able to share any of the compliance standards you have certified your boards to? Have any of these boards been certified for sale in a consumer product? I ask because FCC Class B radiated emissions limits (for example) are tricky to meet, and the design requirements to get there are frequently not well understood.
